❓ Frequently Asked Questions
What is mental math?
Solving math problems in your head without calculators or paper by using strategies such as decomposing numbers, rearranging operations, estimating, and spotting patterns.
What is the distributive property and how can you use it in mental math?
Distributive: a(b+c) = ab + ac. Use it to break numbers apart: 7×13 = 7×(10+3) = 70+21 = 91.
How can you break numbers apart to simplify calculations?
Split numbers into easier parts (tens and ones) and combine. Example: 47+36 = (40+30) + (7+6) = 70+13 = 83.
How can rounding and estimation speed up mental math?
Round to nearby friendly numbers to estimate, then adjust. Example: 87×6 ≈ 90×6 = 540; actual product is 522 (adjust by −18).
