Answer 1

Step-by-step explanation:

Subtraction

Subtraction is the term used to describe how we ‘take away’ one or more numbers from another.

Subtraction is also used to find the difference between two numbers. Subtraction is the opposite of addition. If you have not already done so, we recommend reading our addition page.

The minus sign ‘−‘ is used to denote a subtraction operation, such as 4 − 2 = 2. The '−' sign can be used multiple times as required: for example, 8 − 2 − 2 = 4.

This calculation is correct, but it can be simplified by adding together the numbers we are subtracting. In our example, 8 − 2 − 2 = 4 can be simplified to 8 − 4 = 4 (the two 2s have been added together to give 4, which is then subtracted from 8)
