Since Louie spent money on new clothes, we need to subtract the cost of the shirt and the pants from the original amount of money on his gift card.

Since Sandra spent money on a new dress, we need to subtract the cost of the dress from the original amount of money she earned from babysitting.

You can solve this problem by considering the subtracting equation involved for taking each place value of the numberfromand then combining your results.;, and, which is the answer.

When subtracting with positive and negative numbers, we want to first change the problem into an addition problem to make it simpler to solve.

Step One: Rewrite the first number:

Step Two: Replace the subtracting sign with an addition sign. (When we do this, we have to switch the sign of the second number to its opposite, positive to negative or negative to positive.)

Now we have:

We changed the minus sign to a plus and wrote the opposite of the second number. (In the original problem it was positive 8, so we made it into a negative 8.)

Now that we have an addition problem with two negative numbers, we can just add them together, remembering that the answer stays negative because both numbers are negative.

You can also picture -4 on a number line. Think of moving 8 numbers AWAY from 0. This would mean you would go to -12.

To subtract, borrow afrom thein the tens digit of.

This is the ones digit of the final answer.

Sincewas borrowed from thein the tens digit of, the tens digit becomes a. Subtract theand the tens digit from.

This is the tens digit of the final answer.

The final answer is.
