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, separated by plus or minus signs (e.g., in 3x + 5y, 3x and 5y are terms).

What does it mean to solve an equation?

Back

To solve an equation means to find the value of the variable that makes the equation true (e.g., solving 2y + 4 = 14 gives y = 5).

Front

What is the difference between an equation and an expression?

Back

An equation includes an equal sign and states that two expressions are equal, while an expression does not have an equal sign and represents a value.

Front

What is a constant in algebra?

Back

A constant is a fixed value that does not change (e.g., in the expression 3x + 5, the number 5 is a constant).
