WAStandard form becomes powerful when you know how to multiply and divide it correctly.
Standard form, also known as scientific notation, is used to express very large or very small numbers in a compact way. It is widely used in mathematics, physics, chemistry, and engineering.
In today’s lesson at Wanies Academy, we break down:
• What standard form means (A × 10ⁿ where 1 ≤ A < 10)
• How to multiply numbers in standard form
• How to divide numbers in standard form
• The rules for adding and subtracting powers of 10
• How to adjust answers back into proper standard form
• Common exam mistakes to avoid
Key rules to remember:
Multiplying:
Multiply the numbers. Add the powers.
Dividing:
Divide the numbers. Subtract the powers.
Always ensure your final answer is written correctly in standard form.
This topic is heavily tested in WAEC, NECO, GCSE, and other mathematics exams. Mastering it strengthens your problem-solving skills across STEM subjects.
If you want to improve your mathematical accuracy and confidence in scientific calculations, this lesson is for you.
