PEMDAS is used for these kinds of problems so that you know what step to start with first.
P = Parentheses first
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
First Example:
Using the PEMDAS rule let's start with multiplication then divide then add.
[tex]7+54/3(2) = 7+54/6=7+9=16[/tex]
Second Example:
Using the PEMDAS rule let's start with Exponents then multiplication then addition then subtraction.
[tex]24-4^2*3+15=24-16*3+15=24-48+15=24-63=-39[/tex]
Hope this helps!
