Example Question #11 : 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.
Example Question #1 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
more than times .
more than times is the same as because more means to add and times means muitpilcation.
Example Question #2 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
minus , then multiply .
We want to first subtract and , so we need to set that in parentheses because of the order of operations. Then we can multiply by 20.
Example Question #3 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
First divide and , then multiply .
Because of order of operations, when we have division and mulitplication, we work left to right. So we can first write divided by and then we can multiple by .
Example Question #3 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
First subtract and then dvide by .
Because we want to subtract and , we need to set that off into parentheses so that operation comes before we divide by .
Example Question #5 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
First subtract and , then divide .
Because we want to subtract and first, we need to set that off into parentheses due to the order of operation rules. Then we can do the division of .
Example Question #4 : Write And Interpret Simple Expressions That Record Calculations: Ccss.Math.Content.5.Oa.A.2
Select the equation that reflects the phrase below.
First multiply and then divide by .
Because of the order of operations, when we have multiplication and division we work from right to left. Since we first want to multiple and , we do then we do the
