Question

My homework said"Solve using the standard algorithm. Check your quotient and remainder by using multiplication and addition."

Answer 1

84 divided by 2 = 42.

2 goes into 8 four times, so there would be your 4.
 Then 2 goes into 2 one time, and there would be your 2.

You check your answer by multiplying 42 by 2, which would give you, 84.

Answer 2

Divide 84 by 2 and u get 42
