Subtraction

                                    

 

What is Subtraction?

Subtraction is a process that we use to find the result of taking numbers away from each other, for example: 45 minus 12 equals 33

In mathematics we usually use symbols instead of words though, for subtraction sums you need to know that:

the symbol for minus is -       and          the symbol for equals is =

 

so the above sum would change to be: 33 - 12 = 45

 

On paper it is easier to solve these sums if you write them out in a different way:

  45
- 12
--------
  33
