Expressions and GEMDAS Review #1

Choose the expression that represents the story problem: Clara spent $12 on a necklace from Shein. She then bought 4 hair clips for $2 each. How much money did Clara spend in all?

• 12 x 4 + 2

• 12 + 4 x 2

• (12 + 4) x 2

• 12 - 4 + 2

Answer explanation

Clara spent $12 on a necklace and 4 hair clips at $2 each. The total cost for the clips is 4 x 2 = 8. Therefore, the total amount spent is 12 + 8, which is represented by the expression 12 + 4 x 2.

Choose the expression that represents the story problem: Bunny made 7 carrot cookies for herself. She then made 16 more carrot cookies and split them evenly between herself and 3 friends. How many carrot cookies does Cindy have now?

• 7 x 16 - 4

• 7 ÷ 16 - 4

• 7 - 16 ÷ 4

• 7 + 16 ÷ 4

Answer explanation

Bunny starts with 7 cookies and makes 16 more. She splits the 16 cookies among herself and 3 friends, totaling 4 people. Each gets 16 ÷ 4 = 4 cookies. Thus, Bunny has 7 + 4 = 11 cookies, represented by 7 + 16 ÷ 4.

Choose the correct expression and then evaluate the expression: 8 less than the product of 9 and 3.

• 8 - 9 + 3

• 8 - 9 x 3

• 9 x 3 - 8

• 9 x (8 - 3)

Answer explanation

The phrase '8 less than the product of 9 and 3' translates to '9 x 3 - 8'. Evaluating this gives 27 - 8 = 19, making '9 x 3 - 8' the correct expression.

Choose the correct expression and then evaluate the expression: subtract 17 and 5, then divide by 3.

• 17 - 5 ÷ 3

• 3 ÷ (17 - 5)

• (17 - 5) ÷ 3

• 17 ÷ 5 - 3

Answer explanation

Which word phrase represents the numerical expression 49 ÷ 7 + 3?

• 49 more than the quotient of 7 and 3

• 49 divided by the sum of 7 and 3

• 3 more than the product of 49 and 7

• 3 more than the quotient of 49 and 7

Answer explanation

The expression 49 ÷ 7 + 3 can be interpreted as '3 more than the quotient of 49 and 7', which matches the correct choice. The other options do not accurately represent the operations in the expression.

Choose the expression that represents the story problem: Sarah had 15 apples. She gave 4 apples to each of her 3 friends. How many apples does Sarah have left?

• 15 - 4 x 3
