Combining Like Terms: The Math Magic

Combining Like Terms

Learn the math magic of combining like terms to simplify expressions and solve equations. Master this fundamental concept to excel in algebra and beyond.

Combining Like Terms

Combining like terms is a fundamental concept in algebra. It involves simplifying expressions by adding or subtracting terms that have the same variables and exponents. To combine like terms, add or subtract the coefficients while keeping the variables and exponents unchanged. Remember to only combine terms that are alike. Here are some examples:

• 3x + 2x = 5x
• 4y - 2y = 2y
• 7a^2 - 3a^2 = 4a^2
