<h3>Answer: Exponents is done first (evaluate

P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
With the expression we have two operations going on here: exponents and addition.
Since exponents comes before addition (E comes before A in PEMDAS), this means we evaluate first, then add later.
