Methods of addition and subtraction removal numbers over 100

Subtracting by ‘taking away’

If you have 5 items and you take 2 away, the number remaining is 5 − 2, which is 3.

For example, ‘I had 5 pencils but my sister took 2 away, so now I have 3’.

In this case, 2 is subtracted from 5 to give 3. On a number line, this can be illustrated

as shown.
