Question

James is painting his 10 by 8 foot bedroom wall that contains a 2 by 3 foot window. How many square feet of wall does he need to paint
Ms. Sue
(10 * 8) - 6 = _______ square feet

The answer is 74 square foot, because 10 multiplied by 8 equals to 80, 3 multiplied by 2 equals 6. 80 minus 6 equals to 74 square foot. So James has to paint 74 square foot.
I still dont get this even when she just explained it I need so some help with this question.
