Evaluating Numerical Expressions

Andrea has 6 one-dollar bills and 3 five-dollar bills. The expression below represents the total amount of money Andrea has.

(6 x 1) + (3 x 5)

• (6 + 1) x (3 + 5)

• (3 x 5) + (6 x 1)

• (6 + 1) + (3 + 5)

• (3 x 5) x (6 x 1)

Which number expression is the same as the comparison below? 16 times as much as 4

• 16 x 4

• 16 + 4

• 16 - 4

Which number expression is the same as the comparison below?

ten times as much as five

• 10 + 5

• 10 - 5

• 10 x 5

In which numeric expression will 4 + 5 be the first step in simplifying?

• 16 - 4 + 5

• 4 + (5 x 2)

• 9 x (4 + 5) - 2

• 4 + 5[9 - (6 + 2)]

Mary has 3 boxes of key chains. There are key chains in each box. Each key chain has 6 beads. The expression below shows the total number of beads on these key chains.

(3 x 8) x 6

Which expression could also be used to fin the total number of beads on these key chains?

• 6 x (3 x 8)

• 6 + (3 x 8)

• 6 x (3 + 8)

• 6 + (3 + 8)

• Add 5 and 3.

• Divide 15 by 5.

• Multiply 8 by 40.

• Subtract 15 from 40.

Evaluate the numerical expression.
