What is a constant in algebra?

Back

A constant is a fixed value that does not change. For example, in the expression 8x + 5, the number 5 is a constant.

What is a coefficient?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 3x, the number 3 is the coefficient.

Front

What is a variable?

Back

A variable is a symbol used to represent an unknown value. Commonly, letters like x or y are used as variables.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operators (like +, -, *, /) that represents a value. For example, 2x + 3 is an algebraic expression.

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing an equal sign (=). For example, 2x + 3 = 7 is an equation.

Front

What is an exponent?

Back

An exponent indicates how many times a number (the base) is multiplied by itself. For example, in 2^3, the exponent 3 means 2 is multiplied by itself 3 times (2 * 2 * 2).

Front

What is a term in algebra?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both multiplied together. For example, in 4x^2 + 3x + 7, the terms are 4x^2, 3x, and 7.

What is an operator in algebra?

Back

An operator is a symbol that represents a mathematical operation. Common operators include addition (+), subtraction (-), multiplication (*), and division (/).

Front

What is a polynomial?

Back

A polynomial is an algebraic expression that consists of one or more terms, where each term is a constant multiplied by a variable raised to a non-negative integer power. For example, 4x^2 + 3x + 2 is a polynomial.

What is a linear equation?

Back

A linear equation is an equation of the first degree, meaning it has no exponents greater than one. It can be written in the form ax + b = c.
