Find an equivalent expression using the Commutative property:
4 x 3 x 5 = 

• 4 + 3 x 5
• 5 x 4 x 3
• 5 + 4 + 3
• 3x + 5

Find an equivalent expression using the Associative property: 
A + ( B + C ) = 

• (A + B) + C
• A + B + C
• (A + B + C)
• none are equivalent

Write an algebraic expression for:
 35 decreased by a number

• 35+n
• 35-n
• n-35

"Subtracted from" and "less than" are terms that mean you need to "turn" or "flip"  the terms around.

• True
• False
