What would you say the answer to this math question is? 16 or -16?

-2^4, or -2 to 4th power.

Came across this when helping my kids with homework.

You can google search questions like that. Makes it easy for us who can't remember back that far to highschool math class. The answer is -16. Got to love google search.

Cheating is the only way I could answer it!

-2 x -2= +4.

+4 x -2 = -8

-8 x -2 = + 16.

So, positive 16.

I think 16, so I asked my DH who's an engineer and math genius and he agreed with me.

-2 to the 4th
-2 x -2 = 4
4 x -2 = -8
-8 x -2 = 16

WAIT. HOLD THE PHONE.

Does order of operations matter in this one?

If it were written this way (-2)^4, it would be +16.

But, if it's not, then it is -16.

Did anyone else read the thread about the X's getting blurry, and the humming and the voices? This does it too!
