Answer:
22,590
Explanation:
Step 1: Use PEMDAS, according to PEMDAS, multiply first. (You might see that some of the operations are in the same place, that is because if for example multiplication is on the left, and division is on the right, do the multiplication first. It is a common misconception to do addition/subtraction first than multiplication/division because they are on the left.)
P = Parentheses 1st
E = Exponent 2nd
M = Multiplication 3rd/4th
D = Division 3rd/4th
A = Addition 5th/6th
S = Subtraction 5th/6th
90 + (50 x 450)
50 x 450 = 22,500
Step 2: Add 90 to the product
90 + 22,500 = 22,590
