The following outline is provided as an overview of and topical guide to arithmetic: Arithmetic is an elementary branch of mathematics that deals with numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms, and the use of such operations to perform more complicated calculations. Arithmetic is fundamental for both pure mathematics and its practical application to science and daily life. In pure mathematics, arithmetic is defined formally for various types of numbers, such as integers, fractions of integers (rational numbers), and real numbers. In practical application, arithmetic is usually approximate, operating on decimal or binary numbers, with rounding.

Order of operations Addition Summation – Answer after adding a sequence of numbers Additive inverse Subtraction – Taking away numbers Multiplication – Repeated addition Multiple – Product of multiplication Least common multiple Multiplicative inverse Division – Repeated subtraction Modulo – The remainder of division Quotient – Result of division Quotition and partition – How many parts are there, and what is the size of each part Fraction – A number that is not whole, often shown as a division equation Decimal fraction – Representation of a fraction in the form of a number Proper fraction – Fraction with a numerator that is less than the denominator Improper fraction – Fractions with a numerator that is any number Ratio – Showing how much one number can go into another Least common denominator – Least common multiple of two or more fractions' denominators Factoring – Breaking a number down into its products Fundamental theorem of arithmetic Prime number – Number divisible by only 1 or itself Prime number theorem Distribution of primes Composite number – Number made of two smaller integers Factor – A number that can be divided from its original number to get a whole number Greatest common factor – Greatest factor that is common between two numbers Euclid's algorithm for finding greatest common divisors Exponentiation (power) – Repeated multiplication Square root – Reversal of a power of 2 (exponent of 1/2) Cube root – Reversal of a power of 3 (exponent of 1/3) Properties of Operations Associative property Distributive property Commutative property Factorial – Multiplication of numbers from the current number to 0
