How to do it in your head (Pick the easy road): Split: if one number has small ones (like 23), do × 20 and × 3 and add. Round and take away: if a number ends in 8 or 9 (like 39), do × 40 and take away × 1. Factor: if a number is in a times table (like 24 = 8 × 3), multiply by one factor, then the other.
