Re Adrian Chiles on the nine times table (Struggling with the nine times table? I have a failsafe method, 21 May), here’s an easier method that doesn’t involve finger contortions: write down 0-9 in a column. Then, starting from the bottom, do the same alongside. Bingo! I taught maths in Strangeways prison and could get anyone to do times tables. Fear of maths is down to bad teaching.

• An easier way to calculate the nine times table is to multiply by 10 and deduct the multiplier. For example, 7×9 = 70-7.
