Because we are multiplying by the sum, which is the answer to an addition problem, we first need to add so we need to put the addition problem in parentheses, then we can do the multiplication. 

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

Because we are dividing by the difference, or answer, from the subtraction problem, we first need to subtract. In order for the subtraction problem to go first, we need to put that in parentheses. 

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

The phrase "more than" means to add. Because we are adding and subtracting in this question, we do not need to use parentheses because with addition and subtraction you work the problem out from left to right. So first we have the addition problem, then we subtract. 

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

The phrase "less than the product" means that we are going to subtract  from the answer of our multiplication problem. Because of our order of operations, multiplication will come beore subtraction so we do not need to use parentheses.

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

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 division problem, then we multiply because it says to find the product of the quotient (answer to a division problem), which means we need to divide first. 

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

Because of our order of operations, the division problem needs to come first. We list the subtraction  last because we are subtracting a number by the quotient, so the quotient needs to be listed first. 

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

 needs to be listed first because that's the number that is getting divided. However, we need to do the multiplication problem first to find out what number we are dividing into , so we need to put the multiplication problem into parentheses. 

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

Difference means the answer to a subtraction problem. Because we are adding a number to the difference, we need to do the subtraction problem first. Since we are adding and subtracting in this question, we do not need to use parentheses because with addition and subtraction you work the problem out from left to right. So first we have the subtraction problem, then we add. 

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

Product means the answer to a multiplication problem. Becuase of our order of operation rules, the multiplication problem will come first, regardless of if it's listed first or second. Then we add. 

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

Because we want to subtract 28 and 17 first, we need to set that off into parentheses due to the order of operation rules. Remember: without parentheses, division would come before subtraction.  The parentheses around (28 - 17) tells you that the subtraction comes first, then we can do the division by 3.
