1 Answer
The answer is 20 and see below for the procedure!
Explanation:
So for this equation, since it is the Order of the Operations, I will be using PEMDAS:
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Note: For multiplication and division, do whichever one that comes first in the equation and same for addition and subtraction. :)
Now, let's start working it out!
Procedure:
Parentheses:
None
Exponents:
None
Multiplication:
I made the problem bold.
Now the equation will be,
Division:
None
Now lets move on to Addition! But, wait a second, Subtraction is before Addition in the equation so we have to do Subtraction first now! Lets solve the subtraction problem in the equation, so let's solve it now!
Subtraction:
I made the problem bold.
The equation now is
Addition:
So our final answer is
