Simplifying Numerical Expressions Using GMA

Ms. Xenos gave these instructions to her math students.

Add 6 and 12.

Multiply the result by 10.

Which expression has the same final answer as in Ms. Xenos' instructions?

• (6 x 12) + 10

• 6 + (12 x 10)

• (6 + 12) x 10

• 6 x (12 + 10)

What is the correct way to simplify this expression?

6 x (12 + 3)

• Add 3 and 12, and then add that sum to 6.

• Add 3 and 12, and then multiply that sum by 6.

• Multiply 6 by 12, and then add 3 to that product.

• Multiply 6 by 12, and then multiply 6 by 3. Then find the difference between these two products.
