 Addition Addition (often signified by the plus symbol "+") is one of the four elementary, mathematical operations of arithmetic; with the others being subtraction, multiplication and division.The addition of t... Addition - Wikipedia
 Subtraction Subtraction is a mathematical operation that represents the operation of removing objects from a collection. It is signified by the minus sign (−). For example, in the picture on the right, there are ... Subtraction - Wikipedia
 Method of complements In mathematics and computing, the method of complements is a technique used to subtract one number from another using only addition of positive numbers. This method was commonly used in mechanical cal... Method of complements - Wikipedia
 Multiplication Multiplication (often denoted by the cross symbol "×", or by the absence of symbol) is one of the four elementary, mathematical operations of arithmetic; with the others being addition, subtraction an... Multiplication - Wikipedia
 Division (mathematics) In mathematics, especially in elementary arithmetic, division (÷) is an arithmetic operation.Specifically, if b times c equals a, written:where b is not zero, then a divided by b equals c, written:For... Division (mathematics) - Wikipedia
 Number theory Number theory (or arithmetic) is a branch of pure mathematics devoted primarily to the study of the integers, sometimes called "The Queen of Mathematics" because of its foundational place in the disci... Number theory - Wikipedia
 Binary arithmetic In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system, or base-2 numeral system, which represents numeric values using two different symbols: typic...
 Arithmetic logic unit In digital electronics, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and bitwise logical operations on integer binary numbers. It is a fundamental building block of the... Arithmetic logic unit - Wikipedia

 Fraction (mathematics) A fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a cer... Fraction (mathematics) - Wikipedia
 Mental calculation Mental calculation comprises arithmetical calculations using only the human brain, with no help from calculators, computers, or pen and paper. People use mental calculation when computing tools are no...
 Ratio In mathematics, a ratio is a relationship between two numbers of the same kind (e.g., objects, persons, students, spoonfuls, units of whatever identical dimension), expressed as "a to b" or a:b, somet... Ratio - Wikipedia
 Büchi arithmetic Büchi arithmetic of base k is the first-order theory of the natural numbers with addition and the function which is defined as the largest power of k dividing x, named in honor of the Swiss mathemati...
 Successor function In mathematics, the successor function or successor operation is a primitive recursive function S such that S(n) = n+1 for each natural number n.For example, S(1) = 2 and S(2) = 3.The successor functi...
 List of undecidable problems In computability theory, an undecidable problem is of a type of calculation which requires a yes/no answer, but where there can not possibly be any computer program that always gives the correct answe...
 Remainder In mathematics, the remainder is the amount "left over" after performing some computation. In arithmetic, the remainder is the integer "left over" after dividing one integer by another to produce an i...
 Lattice multiplication Lattice multiplication, also known as gelosia multiplication, sieve multiplication, shabakh, Venetian squares, or the Hindu lattice, is a method of multiplication that uses a lattice to multiply two m... Lattice multiplication - Wikipedia
 Serial decimal In computers, a serial decimal numeric representation is one in which ten bits are reserved for each digit, with a different bit turned on depending on which of the ten possible digits is intended. EN...
 Quotient In mathematics, a quotient (from Latin: quotiens "how many times", pronounced ˈkwoʊʃənt) is the result of division. For example, when dividing 6 by 3, the quotient is 2, while 6 is called the div...
 NaN In computing, NaN, standing for not a number, is a numeric data type value representing an undefined or unrepresentable value, especially in floating-point calculations. Systematic use of NaNs was int...
