The video introduces terms in algebraic expressions, explaining that terms can be numbers, variables, or combinations of both, separated by addition or subtraction signs. It provides examples of constants, variables, and combinations, and explains how to identify terms in expressions. The video also discusses rewriting expressions to simplify the identification of terms, especially negative ones, by converting subtraction into addition.

What are terms in algebraic expressions?

• Parts of an expression separated by multiplication or division

• Only the variables in an expression

• Parts of an expression separated by addition or subtraction

• Only the numbers in an expression
