Summary

The introduction to algebra focuses on understanding algebraic expressions, distinguishing between expressions and equations, and defining key terms such as variables, constants, terms, coefficients, and various forms of expressions.

- Algebra involves variables and is concerned with finding patterns true for all numbers or solving for specific values.
- Variables can represent all numbers or specific values, while constants remain unchanged.
- Terms are products of constants and variables, and coefficients are the constant factors of terms.
- Expressions are collections of terms joined by addition or subtraction, without equal signs, unlike equations.
- Understanding the distinctions between monomials, binomials, trinomials, and polynomials is crucial for navigating algebraic expressions.
- Linear, quadratic, and cubic terms are defined by the power of the variable they contain, influencing the structure of expressions.
