Apply operations with rational numbers (positive and negative)

In this lesson, we will learn how to apply operations such as addition, subtraction, multiplication, and division using rational numbers, including both positive and negative numbers.

• Rational numbers include all integers, fractions, and decimals that can be expressed as a ratio of two integers.
• Operations with rational numbers follow the same rules as with whole numbers but require careful attention to signs.
• Adding and subtracting rational numbers may involve finding a common denominator or combining like terms.
• Multiplying and dividing rational numbers involves applying the rules for signs: same signs result in a positive product/quotient, different signs result in a negative one.
• Always simplify your final answer if possible.
