Answer 3

I can help you with math problems. To solve the example 15-3*4+2*4, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. This is also known as PEMDAS. Here are the steps:

- First, perform the multiplication and division from left to right. 15-3*4+2*4 becomes 15-12+8. - Next, perform the addition and subtraction from left to right. 15-12+8 becomes 3+8, which is 11.

The final answer is 11. You can check your answer by plugging it back into the original expression and simplifying. 15-3*4+2*4 = 15-3*11+2*11 = 15-33+22 = 4-4 = 0. Since the result is zero, the answer is correct.
