7 - (3 + 5) + (- 3 + 6) / 3 x 5

4

Step-by-step explanation:

Always remember the order of operations: PEMDAS.

7 - (3 + 5) + (-3 + 6)/3 x 5

7 - (8) + (3)/3 x 5 (solve the parantheses first)

7 - 8 + 1 x 5 (3/3 comes first since multiplication and division have the same order; you would go left to right)

7 - 8 + 5 (Multiplication has a higher order than addition and subtraction)

Step-by-step explanation:

Use PEMDAS

7 - (3+5) + (-3 + 6) / 3*5 (solve Parenthesis first)

7 - 8 + 3 / 3 * 5 (solve the division next)

7 - 8 + 1 * 5 (solve the multiplication next)

7 - 8 + 5 (subtract next)

-1 + 5 (lastly add)
