Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression is: (31-30)*(63/7+64/8)

Step 1: Simplify the expression inside the parentheses/brackets. 63/7 = 9 64/8 = 8

Step 2: Perform the addition inside the parentheses. 9 + 8 = 17

Step 3: Now, perform the multiplication outside the parentheses. (31 - 30) * 17

Step 4: Finally, solve the expression. (1) * 17 = 17

So, the result is 17.
