What is the Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped when adding does not change the sum. For example, (a + b) + c = a + (b + c).

What is the Commutative Property of Multiplication?

Back

The Commutative Property of Multiplication states that the order in which two numbers are multiplied does not change the product. For example, a × b = b × a.

What is the result of -2 × (-5) × (-1) × (-9)?

Back

The result is Positive.

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 by distributing the multiplication.

What is a rational number?

Back

A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, where p is the numerator and q is the denominator (q ≠ 0).

Front

How do you multiply two rational numbers?

Back

To multiply two rational numbers, multiply the numerators together and the denominators together. For example, (a/b) × (c/d) = (a × c) / (b × d).

Front

How do you divide two rational numbers?

Back

To divide two rational numbers, multiply the first rational number by the reciprocal of the second. For example, (a/b) ÷ (c/d) = (a/b) × (d/c).

What is the result of multiplying a positive number by a negative number?

Back

The result is a negative number.
