This video tutorial teaches how to collect like terms in algebraic expressions. It starts with simple examples using variables a and b, then progresses to more complex expressions involving variables x, y, and others. The tutorial covers both addition and subtraction of like terms, demonstrating how to combine terms with different coefficients and variables. By the end, viewers will understand how to simplify expressions by grouping and combining like terms effectively.
