Question

What is the value of the expression? (-4.2)(2)+10

Answer 1

-8.4+10 = 10 - 8.4 = 1.6

Answer 2

Start with multiplication:
-4.2 x 2 = -8.4 (it stays negative because there is an odd number of negative numbers (the -4.2) being multiplied)
Then you add the product and 10 left:
-8.5 + 10 = 1.5
1.5 is your answer
