OMG! Why was I not shown this in Maths class? Column Subtraction Made Easy!
Column Subtraction Made Simple
What a wonderful way of making column subtraction simple for any pupil who is finding it challenging.
It is so simple but yet so effective!
When you are in a position that you have to borrow from a next door place value and the first number is a multiple of 10,100, 1000…., simply subtract 1 from each of the numbers and if by magic the column subtraction becomes a lot easier!
