Example Question #51 : Order Of Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is parentheses, exponents, multiplication, addition, and subtraction. We will work the parentheses first, follow by multiplication then subtraction, then the exponent, multiplication, and finally addition. So we have 
Example Question #52 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is a set of parentheses, we would do that first.
In accordance with PEMDAS, we first did the parentheses, then multiplied, then added.
Example Question #53 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is a set of parentheses, we would do that first.
In this order, you can see that we first added what was in the parentheses, then we multplied, then added.
Example Question #54 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is a set of parentheses, we would do that first.
First we do what is in the parentheses, then multiply, then subtract.
Example Question #55 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is a set of parentheses, we would do that first.
First we did what was in the parentheses, then multiplied, then subtracted.
Example Question #56 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is a set of parentheses, we would do that first.
First we did what was in the parentheses, then added, then subtracted.
Example Question #57 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is no set of parentheses, we can skip rght to the "M" of PEMDAS, multiplication.
Example Question #58 : Order Of Operations
Think PEMDAS: Parentheses, exponents, multiplicaiton, division, addition, subtraciton.
For this problem, since there is no set of parentheses, the first thing we do is multiplication, then addition, then subtraction.
Example Question #56 : Order Of Operations
Use the proper order of operations to solve the following:
1. Solve for everything in parentheses first
2. Perform all multiplication or division
3. Perform addition or subtraction
Answer =
Example Question #1 : Use Parentheses, Brackets, Or Braces In Numerical Expressions And Evaluate These Expressions: Ccss.Math.Content.5.Oa.A.1
Solve:
When solving this problem, remember order of operations PEMDAS. The parentheses come first, followed by the multiplication, and then addition.
