Today you are going to learn how to check addition and subtraction problems with the inverse operation.
“Inverse” means “Equal and Opposite” 2 miles 2 miles Same distance, but in the opposite direction.
“Inverse” means “Equal and Opposite” 2 miles 2 miles Same distance, but in the opposite direction. 3 apples + 4 apples = 7 apples.
“Inverse” means “Equal and Opposite” 2 miles 2 miles Same distance, but in the opposite direction. 3 apples + 4 apples = 7 apples 7 apples – 4 apples = 3 apples 7 apples – 3 apples = 4 apples Addition and Subtraction are Inverse Operations.
