Subtraction is much easier once it is realised that it is the inverse (or opposite) of addition. Many subtraction questions can be answered by adding on, but children are expected to know subtraction facts to at least 20 (eg know that 11 – 4 = 7). Knowing these facts is just as important as knowing ‘tables’. They will also be working with 2-digit numbers, especially multiples of 10. The 2014 Programme of Study suggests that recording subtraction in columns will help prepare for formal written methods in later years.

Some excellent mental arithmetic work on subtracting a single digit from a 2-digit number.
