Sometimes, copying and pasting doesn't work on this board.

7 (-7) -7 (2-3)/ 2(-6+9)
Answered by Ms. Sue
The numerator:

7 (-7) -7 (2-3)
-49 - (-7 * -1)
-49 - 8 = 41

Denominator:

2(-6+9)
2 * 3 = 6

7 (-7) -7 (2-3)/ 2(-6+9) = 41/6 = <b>6 5/6</b>

Note: When you multiply a negative and a positive number, the answer will be negative. Two negatives multiplied together yield a negative answer.

Oops! Obviously, I was wrong. I reworked the problem and found my mistakes.

7 (-7) - 7 (2-3)
______________________
2 (-6 + 9)


Numerator:
-49 - 7 (-1)
-49 - (-7)
-49 + 7 = -42

Denominator:
2 (-6 + 9)
2 (3) = 6

<b>Answer:

-42/6 = -7</b>
