Step-by-step explanation:
you are subtracting a negative number, therefore you are adding the number
The total cost of the dinner with a pre-tax tip would be $65.78. If you paid this with a $100 bill, you would get $34.22 back.
12 x 2 = 24
When you multiply two negative numbers, the answer will be a positive
When you multiply one negative and one positive, the answer will be negative.
Using that rule:
(-12)(-2) = 24
24 is your answer
