How do you solve 26 × 20?

Answer

26 × 20 = 26 × (2 × 10) = (26 × 2) × 10 = 52 × 10 = 520 Or: 26 × 20 = 26 × 2 tens = 52 tens = 520

Card 7Grid Method

Using the grid method, how do you calculate 15 × 14?

Answer

Split into: 15 = 10 + 5, 14 = 10 + 4 × | 10 | 4 -----|-----|----- 10 | 100 | 40 5 | 50 | 20 Add all parts: 100 + 40 + 50 + 20 = 210 So 15 × 14 = 210

Card 8Division with Remainders

What does remainder mean in division?

Answer

Remainder is the number left over when one number doesn't divide evenly into another. Example: 17 ÷ 5 = 3 remainder 2 Because 5 × 3 = 15, and 17 - 15 = 2 So 2 is the remainder.
