Unit 1 Test: Pre-Algebra (Final)

Front

Identify the property of multiplication shown by the equation: (4a · 1)5b = 4a(1 · 5b)

Back

Associative Property of Multiplication: This property states that the way in which numbers are grouped in multiplication does not change their product.

Front

Evaluate the expression –15 – (–20) – 40.

Back

–35: When subtracting a negative number, it is equivalent to adding that number.

Front

Order the integers -5, 3, -(-2), and |-6| from least to greatest using <.

Back

-5 < 2 < 3 < 6: The absolute value of -6 is 6, and -(-2) equals 2.

Front

Simplify the expression: 2x^3·x^2=

Back

2x^5: When multiplying like bases, add the exponents.

Front

4x + (5y + 3) = (4x + 5y) + 3

Back

Associative Property of Addition: This property states that the way in which numbers are grouped in addition does not change their sum.

Front

What is the Identity Property of Multiplication?

Back

The Identity Property of Multiplication states that any number multiplied by 1 remains unchanged.

Front

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.

Front

Evaluate: 3(2 + 4)

Back

18: Using the Distributive Property, 3*2 + 3*4 = 6 + 12 = 18.

Front

What is the Zero Property of Multiplication?

Back

The Zero Property of Multiplication states that any number multiplied by 0 equals 0.
