Fraction
A fraction represents a part of a whole or a division of quantities. It consists of a numerator (top number) and a denominator (bottom number) separated by a line.
Coefficient
A coefficient is the numerical factor that multiplies a variable in an algebraic expression. It tells you how many of that variable you have.
Variable
A variable is a symbol (usually a letter like x, y, or z) that represents an unknown or changeable value in a mathematical expression or equation.
Constant
A constant is a fixed value that does not change. In algebra, constants are numbers without variables attached. In an equation, constants remain the same regardless of variable values.
Numerator
The numerator is the top number in a fraction. It tells you how many parts of the whole you have.
Denominator
