My son has a sixth grade math question here. The rule is to add parentheses to this equation so the answer is correct.

9 to the second power - 2 x 15 +16 - 8 = 11

Sorry, I do not know how to type 9 to the sec. without typing it out. Thanks

9^2 - 2 x (15+16) -8 = 11.

81 - 62 - 8 = 11.

9squared - 2 x (15 + 16) - 8 = 11

9sq-2x(15+16)-8=11

 

[JBradley500]

9^2(-2(15+16)-8=11


I think...

15+16=31

31*-2=-62

-62-8=-70

81-70=11

 

[Glenn.Payne]

9²-(2*(15+16))-8=11

81-62-8=11

I think...lol

9^2-2(15+16)-8=11

92-(2x(15+16))-8=11

92=81

tree'd dammit
2x(15+16)=2x31=62
81-62=19
19-8=11

This PEMDAS shit again. A solution for a problem that didn't exist.

81 - 62 - 8 = 11.

correct
