calculate the value of the expression

Question

4 plus the quantity 9 plus 7 minus the quantity 5 plus 8

Answer 1

To calculate the value of the expression, we follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

The expression is:
4 + (9 + 7) - (5 + 8)

First, we simplify the parentheses:
4 + 16 - 13

Next, we perform the addition and subtraction from left to right:
20 - 13

Finally, we subtract:
7

Therefore, the value of the expression is 7.
