5OA2 Mastering Numerical Expressions

Write an expression that represents the sum of 15 and 7, multiplied by 3.

• (15 + 7) x 3

• 15 + (7 x3)

• 15 x 3 + 7

• 3 x (15 + 7)

Interpret the expression 4 x (9 - 5) without calculating it.

• Subtract 5 from 9, then multiply the result by 4

• Multiply 4 by 9, then subtract 5

• Multiply 4 by 5, then subtract from 9

• Subtract 4 from 9, then multiply by 5

• Add 8 and 6, then divide the sum by 2

• Divide 6 by 2, then add 8 to the quotient

• Multiply 8 by 6, then divide by 2

• Add 8 to 6, then multiply by 2

Write an expression for "the product of 5 and the sum of 8 and 2."

• 5 x 8 + 2

• 5 + (8 x 2)

• (8 + 2) x 5

• 5 x 8 x 2

How would you express "subtract 4 from the product of 6 and 3"?

• 6 x 3 - 4

• 4 - (6 x 3)

• (6 - 4) x 3

• 6 x (3 - 4)

If you have the expression 12 - (3 + 2) x 4, what operation would you perform first?

• Subtraction

• Addition

• Multiplication

• None of the above

Create an expression that shows the difference between 20 and the product of 2 and 5.

• 20 - 2 x 5

• (20 - 2) x 5

• 2 x (20 - 5)

Write an expression for "the quotient of 18 and the sum of 3 and 3."

Interpret the expression (7 - 4) x (2 + 3) without calculating it.

• Subtract 4 from 7, then add 2 and multiply by the 3

• Subtract 4 from 7 and add 2, then multiply the result by 3

• Subtract 4 from 7, then add the result to the sum of 2 and 3

• Subtract 4 from 7 and then multiply the result by the sum of 2 and 3
