Front

What is the Commutative Property?

Back

The Commutative Property states that changing the order of the numbers in an operation does not change the result. For example, a + b = b + a.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum.

Front

What is the definition of a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the coordinates of the origin?

Back

(0, 0)

Front

What is the difference between a rational and an irrational number?

Back

A rational number can be expressed as a fraction \(\frac{a}{b}\) where a and b are integers and b ≠ 0. An irrational number cannot be expressed as a simple fraction.
