+188 \((-2)^4 - 2^4 + (-3)^3 - 3^3\)
I was wondering how to attack this problem
+636 Ok here's my solution,
\(\begin{align*} (-2)^4 &= (-2)(-2)(-2)(-2) = 16,\\ 2^4 &= 2\cdot 2\cdot 2\cdot 2 = 16,\\ (-3)^3&= (-3)(-3)(-3) = (9)(-3) = -27,\\ 3^3 &= 3\cdot3\cdot3 = 27, \end{align*}\)
\((-2)^4 -2^4 + (-3)^3 - 3^3 = 16-16 -27-27 = \boxed{-54}.]\)
So the thing to take away in this question is to always remember that in solving these questions the order of operations in KEY!!!

+188 Thanks, Ducky! but what about factorials and brackets how do they fit in?
+636 This image is excellent I recommend to view it!
