Use the order of operations to simplify 8+7x6-3x4+6x7

To simplify this expression using the order of operations (also known as PEMDAS), we start by evaluating any parentheses or brackets. In this case, there are none.

Next, we evaluate any exponents or square roots. Again, there aren't any in this expression.

After that, we perform any multiplication or division, working from left to right.

8 + 7x6 = 8 + 42 = 50

50 - 3x4 = 50 - 12 = 38

Finally, we perform any addition or subtraction, also working from left to right.

38 + 6x7 = 38 + 42 = 80

Therefore, the simplified expression is 80.
