Question

If you subtract 7 from the product of 8 and 9, what is the result

Answer 1

65

Explanation:

The given written expression can be translated into the following equation:

`(8*9) - 7`

From here, we follow the order of operations, which is also known as PEMDAS -- an acronym to instruct which parts of the equation must be solved first.

PEMDAS stands for:

• parentheses,
• exponents,
• multiplication and division (whichever comes first when reading the expression left to right), and
• addition and subtraction (whichever comes first when reading the expression left to right).

Because we have values within the parentheses, we solve this part of the equation first.

8 x 9 = 72

Now, substitute this value back into the original equation and solve:
(8 x 9) - 7
72 - 7
65

Subtracting 7 from the product of 8 and 9 yields the answer of 65.
