Answer 3

To solve the given expression, let's break it down step by step:

90 + 87 - 75 * 99 - 80 - 81 + 69 * 55 + 76 - 86

First, let's perform the multiplication and division operations from left to right:

90 + 87 - 7425 - 80 - 81 + 3795 + 76 - 86

Next, let's perform the addition and subtraction operations from left to right:

(90 + 87) - 7425 - 80 - 81 + 3795 + 76 - 86

177 - 7425 - 80 - 81 + 3795 + 76 - 86

Now, let's continue evaluating the expression:

177 - 7425 = -7248

-7248 - 80 = -7328

-7328 - 81 = -7409

-7409 + 3795 = -3614

-3614 + 76 = -3538

-3538 - 86 = -3624

Therefore, the value of the expression 90 + 87 - 75 * 99 - 80 - 81 + 69 * 55 + 76 - 86 is -3624.
