Tables 17 and 18 — Tables & Multiplication Mastery

How it works

Ten and a bit — “18 × n = 10 × n + 8 × n”

1. 17 × n = 10 × n + 7 × n.
2. 18 × n = 10 × n + 8 × n (or double the 9 table).
3. Add the two parts.

Use it for: Larger multiplication, factors and long division in Class 4–6.

Worked example: 17 × 6 = 102
