If you are asking how to solve this question, I can help:
First, use the Order of Operations. Parentheses and brackets go first, then exponents, then division and multiplication (depends on which one appears first from left to right), then addition and subtraction (also determined by order of appearance). This problem has a set of parentheses, so first solve that.
7+8 is 15, so then write out complete equation
72- 15 • 4
Multiply 15 by 4 because multiplication is ahead of subtraction in order of operations

Multiply 15 by 4 because multiplication is ahead of subtraction in order of operations
=72-60
=12
So the answer of the above equation is 12.
Follow the order of operations.
B - brackets first
E - exponents do next
D- division
M- multiplication
A- addition
S- subtraction
72 -4 ( 7+8)
72 -28 -32 = 12
72-(7+8)*4
72-15*4
72-60
12
Good Luck! :D
12.
