question

Add.

2.7 + ^–6.1 =

key idea

To add numbers with different signs, subtract the lesser absolute value from the greater absolute value. The sum will have the same sign as the number with the greater absolute value.

solution

You are adding two numbers with different signs, so subtract the lesser absolute value from the greater absolute value:

6.1 − 2.7 = 3.4

Since the number with the greater absolute value is negative, the result must also be negative:

3.4

→

^–3.4

So:

2.7 + ^–6.1 = ^–3.4
