JSS Number Bases Lesson
JSS Number Bases Lesson JSS Mathematics: Number Bases This lesson explains number bases in a simple way for JSS students. It includes worked examples from base 10 to other bases and from base 2 to base 10. 1. Meaning of Number Bases What are number bases? A number base tells us how many digits a counting system uses. The common bases are base 10, base 2, base 5, base 7, and base 8. Base 10 uses digits 0–9 . Base 2 uses only 0 and 1 . 2. Base 10 to Another Base Method Divide the number repeatedly by the new base. Write the remainders from bottom to top. Example: 657₁₀ to base 7 3. Base 2 to Base 10 Method Expand the binary number using powers of 2, starting from the right. 1011₂ = 1×2³ + 0×2² + 1×2¹ + 1×2⁰ Worked Examples: Base 10 to Other Bases Example 1 Convert 657₁₀ to base s...
