What is an algebraic expression?

• Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values.

What is an algebraic equation?

• An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other.

How do you write verbal expressions and equations into algebraic expression and equation or vice versa?

• In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x² − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power 1/2, √((1-x²)/(1+x²)) is also an algebraic expression.
