Answer:

Follow PEDMAS to get to #15#

Let's start with the original:

#5(7-4)#

The order of operations (often referred to as PEDMAS) asks us to do Parentheses first. So we'll do the math inside:

Answer:

#15#

Explanation:

You have a choice of methods.

You can work out the bracket and then multiply, or use the distributive law, multiply first and then subtract.

Both methods will give the same answer.

#5(7-4) = 5xx3 = 15#

OR

#5(7-4) = 35 -20 = 15#
