What are Significant Figures and How Students Can Calculate Them Easily?
The significant figures are used to find the accuracy of numbers in practical estimation. It is essential to round off a long figure so we can understand the number easily. We are using certain rules to round off a number; the same rules are implemented by the significant figures calculator. Sometimes it becomes difficult to decide which number to consider and which number we need to ignore.
The significant figures are used precisely to find the result correctly. The significant figures are used when we are dealing with very small and large quantities in Mathematics. There are certain rules to follow when you are extracting a significant figure from a figure. We do need to implement the significant figure at the workplace to make our estimation more precise and accurate.
This article discusses the various rules of the significant figure to convert the figure is easy to understand.
Rules of the significant figures:
There are certain significant figures and we need to follow them while doing the calculations. We can use the sig fig calculator to find the significant figure of a number. The rules of the significant figures are as follows:
Rule of non-zero numbers:
We need to consider all the non-zero numbers as significant numbers regardless of their position in the number. We consider them significant, and there is always an impact of these numbers in the estimation. The significant digits calculator is going to apply all the rules of the significant figure. The non-zero number always has an impact on the estimation, whether they are small or large, like 5.32222223 m/sec. To apply the rules of the non-zero on the estimation, enter the values in the significant figures calculator and press calculate.
Rule of Zero numbers:
The Zeros that are coming in between the non-zero numbers are considered to be significant numbers as they have an impact on the final result of the calculations and check the number by the sig fig converter. The zeros coming between the decimal numbers become significant as they are weighted due to their position in the figure, like 5.50005 m/sec
Rule of leading Zero:
The leading Zeroes coming after the non-zero numbers are considered to be insignificant in the estimation as they have no role in the total estimation or calculations. Consider the number 5.5000 m/sec; here, all the leading Zeros are insignificant as they have no impact on the overall estimation.
Rule of trailing Zero:
The trailing Zeros would become significant if it has a decimal after them, and these Zeroes are considered significant in the estimation and have an impact on the estimation. Consider the number 5.0001 m/sec; now, these Zeros would become significant numbers. The rules of the trailing zero can be applied easily by the significant figures calculator.
These rules would be consistent when we are calculating the significant figure in the estimations.
Why do we round off a number?
The significant figures are critical when we are going to find precise and accurate results. It is impossible for us to read a long figure like 3.2543331. We need to round off the figure to understand it more accurately. The significant number calculator makes the estimation easy for us as these tools can be implemented on long figures, and we can handle and extract the result precisely when dealing with significant figures in the workplace.
The number 3.2543331 is accurate but not easy to understand. We round off the figure and make it 3.25 and make it an easy number to understand for ourselves. You can see we can understand the number 3.25 easily, and it is accurate too.
Conclusion:
When we are doing the estimation in the lab, we may be dealing with the smallest figure or dealing with the large numbers. In both cases, we do need the significant figure to make our estimation more precise and easy to understand. The significant figures calculator
make the task much simpler for us. You need to apply the rules on the values to convert the number according to the significant number rule.

The federal government has announced the reopening of the 47 unity schools earlier shut down due to security concerns on November 21.
This was disclosed in a statement by the Federal Ministry of Education on Thursday.
It said that the decision to reopen the affected colleges across the country reaffirmed its unwavering commitment to safeguarding students and ensuring the continuity of education.
On November 18, 2025, over 20 schoolgirls were kidnapped by unidentified armed men from the Government Girls Comprehensive Secondary School in Maga, Kebbi state.
Just three days later, on November 21, about 303 students and 12 teachers were kidnapped at St. Mary’s Catholic Primary and Secondary School in Papiri, Niger state.
In response, the federal government shut down 47 Federal Unity Colleges, and some states including Katsina, Taraba, and Niger also closed schools or restricted school activities, particularly boarding institutions.
Rights group including Human Rights Watch lamented that while these measures were aimed at protecting students, they disrupted learning for thousands of children, denied them access to education, and the social and psychological support schools provide.

Online learning platforms, Coursera and Udemy, have reached an agreement to merge in an all-stock transaction, with the combined company’s implied equity value estimated at approximately $2.5 billion.
The agreement, unanimously approved by both companies’ boards of directors, stipulates that Udemy shareholders will receive 0.8 shares of Coursera common stock for each Udemy share held.
Upon completion of the merger, Coursera shareholders are expected to own about 59 per cent and Udemy shareholders approximately 41 per cent of the new entity on a fully diluted basis.
The combined company will continue under the Coursera name, and maintain its headquarters in Mountain View, California.
Coursera, founded in 2012 by Mr Andrew Ng and Ms Daphne Koller, is an online learning platform with 191 million registered users as of September 30, 2025. It collaborates with over 375 universities and industry partners to offer courses, specialisations, professional certificates, and degrees.
The platform includes features such as generative AI (gen AI) tools (Coach, Role Play, Course Builder) and role-based solutions (Skills Tracks) to support scalable and personalised learning. Coursera is used by institutions for workforce development in fields such as gen AI, data science, technology, and business.
Udemy is a platform that provides on-demand, multi-language courses to help companies and individuals develop technical, business, and soft skills. It uses AI to offer personalised learning experiences and supports workforce development in a changing workplace.
Mr Greg Hart, currently CEO of Coursera, is set to lead the enlarged organisation as CEO after the merger.
The board will consist of nine members. Six from Coursera’s board, including chairman Mr Ng and CEO Mr Hart, and three from Udemy’s board.
“We’re at a pivotal moment in which AI is rapidly redefining the skills required for every job across every industry.
“Organisations and individuals around the world need a platform that is as agile as the new and emerging skills learners must master,” Mr Hart said.
The combination is said to create a complete ecosystem of top instructors supported by AI tools, data-driven insights, and broader distribution, enabling more engaging, personalised, and dynamic learning at scale.
Projected operational efficiencies include anticipated annual run-rate cost synergies of $115m within two years after closing.
Udemy CEO, Mr Hugo Sarrazin said: “For more than 15 years, Udemy has helped millions of people master in-demand skills at the speed of innovation.
“Through this combination with Coursera, we will create meaningful benefits for our learners, enterprise customers, and instructors, while delivering significant value to our shareholders, who will participate in the substantial upside potential of the combined company.”
The merger is anticipated to close in the second half of 2026, pending regulatory clearances, approval by both companies’ shareholders, and other customary closing conditions.

Global cryptocurrency platform, Luno and AltSchool Africa, an accredited online learning platform, have announced a strategic partnership aimed at demystifiing crypto to 15,000 Nigerians.
The initiative at that scale makes it Africa’s largest crypto education programme.
According to a joint statement on Wednesday, this is a significant step in Luno’s continued efforts to strengthen trust in digital assets and support safer participation in the digital economy.
This is hinged on Africa’s fast-growing digital finance landscape where 33 per cent of the country’s population already engage with digital assets, and a rapidly growing youth population are eager to participate in the digital economy.
According to the statement, the partnership aims to bridge the knowledge gap by providing structured, practical, and safe crypto education.
This will be done by combining Luno’s experience in promoting safe crypto participation with AltSchool Africa’s capability in delivering accessible digital skills training.
“The course directly addresses the misinformation and financial risks associated with unregulated digital assets, while demonstrating real-world applications tailored to African contexts,” the joint statement added.
The initiative will be implemented in three cohorts of 5,000 learners each. Applications for Cohort 1 will be open from January to February 2026, with the course commencing in March 2026. Cohort 2 participants will gain access to the course in July 2026, while Cohort 3 participants will begin the programme in November 2026.
The programme will be led by Web3 expert Mr Abdulsamad Tiamiyu, who will provide a practical, Africa-focused introduction to cryptocurrency, showing how it can be used for saving, remittances, global trading, and entrepreneurship.
The curriculum consists of five core modules and is designed to be completed within three to four weeks.
Learners benefit from up to one year of access to all course materials, including online, self-paced video lessons, slides, quizzes, and case studies. The course combines theory with hands-on experience, where learners interact with wallets, exchanges, stablecoins, and research tools like CoinGecko and Etherscan.
According to the organisers, this approach gives learners the tools to confidently use digital currencies in everyday financial activities. Successful learners, upon passing the assessments, earn an AltSchool Africa Certificate of Completion.
Speaking on the partnership, Mr Ayotunde Alabi, CEO of Luno Nigeria, said: “This initiative is a crucial intervention in Africa’s digital ecosystem. As crypto adoption accelerates, formal literacy must grow alongside it, so individuals can benefit safely and meaningfully,”
“Our partnership with AltSchool Africa is a deliberate step toward that goal and a foundational investment in the integrity of the industry. By delivering structured, high-quality education, Luno is helping ensure that Africans can participate confidently, securely, and sustainably – turning what is often seen as risk into real economic opportunity,” he added.
Adding his input, Mr Adewale Yusuf, Co-founder and CEO of AltSchool Africa, said “This partnership between AltSchool and Luno is a major step toward financial education that truly serves Africans and helps people gain the knowledge and tools they need to understand crypto with confidence and use it in practical, life-changing ways.”
The programme is open to Nigerian residents aged 18 and above who are able to commit to completing it within four weeks. Applicants must have a Luno account or create one before enrolling.
Starting January, Interested participants are encouraged to submit application through the AltSchool Africa portal, with scholarship decisions communicated within one week.
