Please don't use "x" for mult.; instead, use " * ."

You must obey Order of Operations rules.  That would mean doing (5-3) before anything else.  This boils down to (2), so that you have:

(2+3) + 4^2 * 2

Next, take care of that exponentiation (before mult. or add'n.).

(5) + 16 * 2 = 37 (answer)
Hey!


Alright, before we solve this problem it's important to know that we should start by doing what's inside the parenthesis. The reason this should be our first step is because of P.E.M.D.A.S.

Original Equation :
(2+3) + 4^2 · (5 - 3) = ?

New Equation {Changed by Adding What's in the Parenthesis} :
5 + 4^2 · 2 = ?

Now, according to the order of P.E.M.D.A.S., we can go ahead and solve that exponent in the equation.

Old Equation :
5 + 4^2 · 2 = ?

New Equation {Changed by Solving Exponent} :
5 + 16 · 2 = ?

Again referring back to P.E.M.D.A.S., the next step would be to multiply.

Old Equation :
5 + 16 · 2 = ?

New Equation {Changed by Multiplying 16 and 2} :
5 + 32 = ?

And finally, it's just basic addition.

Old Equation :
5 + 32 = ?

Solution :
37

So, now we know that (2+3) + 4^2 x (5 - 3) equals  37.

Hope this helped!
