Algebra is like a mathematical tool for solving
puzzles with letters and numbers. It helps us figure
out unknown values in equations and work with
patterns and relationships in math problems.
What is Algebra?
An algebraic expression is built from integer constants,
variables, and algebraic operations.
Variables represent unknown values, such as x, y, a, b,
etc.
Example: 6x + 5 is an algebraic expression.

Algebraic Expressions
At least one expression in an
equation must contain a variable.
The LHS of an equation is equal to
the RHS.
Equations always have an equality
sign.
The order of expressions in an
equation can be interchanged
without changing the equation's
meaning.

Statements can be translated into equations.
For example, "The sum of four times x and 12 is 38"
becomes the equation 4x + 12 = 38.
Similarly, various statements can be converted into
equations to solve mathematical problems.
