To simplify the expression 8 + 7⋅6 - 3⋅4 + 6⋅7, you must follow the order of operations which is PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
First, you must perform multiplication and division from left to right.
7⋅6 = 42
3⋅4 = 12
6⋅7 = 42
The expression now simplifies to 8 + 42 - 12 + 42.
Next, you perform addition and subtraction from left to right.
8 + 42 = 50
50 - 12 = 38
38 + 42 = 80
So, the simplified expression is 80.
