This one looks familiar, but here it is again:
(10 – 6)^2 + 6 • 2 – (3 + 2)^2
4^2 + 6*2 - 5^2
16 + 6*2 - 25
16 + 12 - 25
Now can you get 3?
Show ALL work or explain in details the correct solution: What is the value of (10 – 6)^2 + 6 • 2 – (3 + 2)^2
I know the answer is 3. I need help with the "Show ALL work or explain in details the correct solution" part.

Yes, thanks!
(10 – 6)^2 + 6 • 2 – (3 + 2)^2
brackets first
= 4^2 + 6*2 - 5^2
exponents...
= 16 - 6*2 - 25
multiplication before addition or subtraction
= 16 - 12 - 25
finish it off
= -21 , not 3 as you claim.

oops, typo in 16 - 12 - 25
should be
16 + 12 - 25
= 3
should be
16 + 12 - 25
= 3
