OK. Some interesting stuff. Google say they are different. https://www.google.com/search?q=(-3)%5E2&rlz=1C1CHFX_enUS529US529&oq=(-3)%5E2&aqs=chrome..69i57j0j69i61.309j0j7&sourceid=chrome&es_sm=122&ie=UTF-8 https://www.google.com/search?q=-3%5E2&rlz=1C1CHFX_enUS529US529&oq=-3%5E2&aqs=chrome..69i57j0j69i61.324j0j7&sourceid=chrome&es_sm=122&ie=UTF-8 JavaScript just gets 9. EXCEL gets 9. Win-Scientific calculator gets 9

@TBR you mean they're the same, right? If they're both 9?

My scientific calculator, and my knowledge of math, says that -3^2= -9

@Varrack - I am saying that google does the math as (-3)^2=9 -(3^2)=-9. Excel gets you 9 for each. Q1 without the () is ambiguous.

One is 9 the other -9

Correct kreakin.
