# Arithmetic: What are Identity Elements?

An identity element is a number that allows another number to keep its identity. For instance, 0 is the identity element for addition because adding it to any number doesn't change the number. Similarly, 1 is the identity element for multiplication because multiplying any number by 1 doesn't change the number. It's important to note that identity elements are unique to each operation. This series is about learning arithmetic, including addition, subtraction, multiplication, and division, as well as whole numbers, fractions, decimals, and complex numbers. These concepts are fundamental to other math subjects like algebra, trigonometry, and geometry. Join us every Thursday for Math Camp and don't forget your paper and pencils!
