Mental Mathematics

Beginner lesson

Break numbers into friendly parts, work left to right, and estimate first so you notice wrong answers.

  1. Estimate: round each number and guess the answer.
  2. Split: 47 + 38 = 40 + 30, then 7 + 8.
  3. Combine the parts.
  4. Compare with your estimate.
Worked example: 26 × 4 → (20 × 4) + (6 × 4) = 80 + 24 = 104. Estimate 25 × 4 = 100 — close, so 104 is believable.
