To simplify the expression 8 + 7 * 6 - 3 * 4 + 6 * 7, we use the order of operations (PEMDAS/BODMAS):
First, we perform the multiplication:
8 + 42 - 12 + 42
Next, we perform the addition and subtraction from left to right:
8 + 42 equals 50
50 - 12 equals 38
38 + 42 equals 80
Therefore, the simplified expression is 80.
simplify 8 + 7 . 6 - 3 . 4 + 6 . 7
