Select the equation that reflects the phrase below.

Find the sum of  and  and then divide 

Possible Answers:

Correct answer:

Explanation:

When you are asked to find the sum that means we are going to add. Because the phrase says "then divide" we need to put the addition problem in parentheses because of our order of operations. Then we can divide. 

Remember, order of operations is PEMDAS= parentheses, exponents, multiplication/division, addition/subtraction.  

 

Example Question #91 : Operations & Algebraic Thinking

Select the equation that reflects the phrase below.

Divide the product of  and  by 

Possible Answers:

Correct answer:

Explanation:

When you are asked to find the product that means we are going to multiply. Because we are multiplying and dividing in this question, we do not need to use parentheses because with multiplication and division you work the problem out from left to right. So first we have the multiplication problem, then we divide. 

Remember, order of operations is PEMDAS= parentheses, exponents, multiplication/division, addition/subtraction.  

Example Question #93 : Operations & Algebraic Thinking
