How do you simplify #9xx10+80-78-+17xx7# using the order of operations?
The answer is
Follow the order of operations as given in the acronym PEMDAS.
(M and D have equal weight and are calculated from left to right.)
(A and S have equal weight and are calculated from left to right.
Given:
A negative and a positive make a negative.

To simplify the expression 9x×10 + 80 - 78 ÷ 17×7 using the order of operations (PEMDAS/BODMAS), you first perform any multiplication and division from left to right, then addition and subtraction from left to right.
- 9x × 10 = 90x
- 78 ÷ 17 ≈ 4.588 (rounded to three decimal places)
- Multiply the result of step 2 by 7: 4.588 × 7 ≈ 32.116 (rounded to three decimal places)
Now, rewrite the expression with the simplified values:
90x + 80 - 32.116
Then, you perform addition and subtraction:
90x + 80 - 32.116 ≈ 90x + 47.884
So, the simplified expression is 90x + 47.884.
