Explanation Given Information: The provided expression is ( − 4 ) ( 5 ) + ( − 6 ) ( − 4 ) − 7 ( − 4 ) ÷ 2 ( 7 ) . Formula used: Steps for order of operations are as follows: Step 1. Initially operate operations within parenthesis or group symbols. Step 2: Evaluate powers of number. Step 3: Next, perform multiplication and division from left to right. Step 4: Finally perform addition and subtraction from left to right. Calculation: Consider the following expression: ( − 4 ) ( 5 ) + ( − 6 ) ( − 4 ) − 7 ( − 4 ) ÷ 2 ( 7 ) Initially solve the parenthesis from left to right. The multiplication or division of two positive or negative number is positive and multiplication or division of two number with different sign is negative. Solve the expression by multiplying or dividing then add or subtract the numbers. According to order of operation multiplication and division are performed first, so multiply and divide one by one from left to right: ( − 4 ) ( 5 ) + ( − 6 ) ( − 4 ) − 7 ( − 4 ) ÷ 2 ( 7 ) = − 20 + ( − 6 ) ( − 4 ) − 7 ( − 4 ) ÷ 2 ( 7 ) = − 20 + 24 − 7 ( − 4 ) ÷ 2 ( 7 ) = − 20 + 24 + 28 ÷ 2 ( 7 )
