Question

-200+32(-3+7) - 45(15-20)

Answer 1

153

Explanation:

To simplify the expression -200 + 32(-3 + 7) - 45(15 - 20), you can start by simplifying the parentheses.

-3 + 7 equals 4, and 15 - 20 equals -5.

So the expression becomes:

-200 + 32(4) - 45(-5)

Next, you can perform the multiplications:

32(4) equals 128, and 45(-5) equals -225.

Now the expression becomes:

-200 + 128 - (-225)

To simplify the double negative, you can change it to addition:

-200 + 128 + 225

Finally, you can add the numbers together:

-200 + 128 + 225 equals 153.

Therefore, the simplified expression is 153.
