Question

Subtract: − 5 − 6 from −7 + 3 − 2 by using column method.​

Answer 1

Answer:

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).
