# Types of Arithmetic

In modular arithmetic, the modular additive inverse of x is also defined: it is the number a such that a + x ≡ 0 (mod n). This additive inverse always exists. For example, the inverse of 3 modulo 11 is 8 because it is the solution to 3 + x ≡ 0 (mod 11).

Array

In math, an array refers to a set of numbers or objects that will follow a specific pattern. An array is an orderly arrangement—often in rows, columns or a matrix—that is most commonly used as a visual tool for demonstrating multiplication and division.

Boolean

Boolean complementation finds equivalency in the form of the NOT gate, or a normally-closed switch or relay contact: The basic definition of Boolean quantities has led to the simple rules of addition and multiplication, and has excluded both subtraction and division as valid arithmetic operations.

Cube Root

... so the cube root of 125 is 5 The Cube Root Symbol This is the special symbol that means "cube root", it is the "radical" symbol (used for square roots) with a little three to mean cube root.

Division

Division is one of the four basic operations of arithmetic, the others being addition, subtraction, and multiplication. The division of two natural numbers is the process of calculating the number of times one number is contained within another one.

Exponentiation (Power) Exponent

Exponentiation is a mathematical operation, written as b n, involving two numbers, the base b and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: = × ⋯ × ⏟.

Float (Floating Point Numbers

In computing, floating-point arithmetic is arithmetic using formulaic representation of real numbers as an approximation so as to support a trade-off between range and precision. For this reason, floating-point computation is often found in systems which include very small and very large real numbers, which require fast processing times.

Integer

In algebra, students use letters and symbols in place of numbers in order to solve mathematical equations. In this branch of math, the term "integer" is frequently used. An integer is any whole number, whether that number is positive or negative. Fractions are not whole numbers and, thus, are not integers.

Multiplication

The topic starts with 1-digit multiplication and division and goes through multi-digit problems. We will cover regrouping, remainders, and word problems. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.

NULL

When you use. words[a] the result is a char, which can be implicitly converted into an int and compared to NULL (same as 0) When you say. words[1]=="a"

Object

The four elementary operations addition, subtraction, multiplication and division are commonly referred to as the four arithmetic operations, even though the terms apply to operations on numbers other than integer, rational, or decimal and on mathematical objects of completely different kinds.

Order of Operations

In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.

Resource

An arithmetic sequence has a common difference of 3, and the fifth term of the sequence is seven times the first term of the sequence. List the first seven terms of this sequence.

Square Root

So this is equal to-- and let me write it this way. Normally, you could skip this step. But you could write this as the square root of-- and instead of 100, 100 is the same thing as 10 times 10. …

String

String Arithmetic As stated earlier today, the + operator has a double life outside the world of mathematics. It can be used to concatenate two or more strings.

Subtraction

Although addition is the opposite of subtraction, it is also true that every addition problem can be rewritten as a subtraction problem. For example, the problem 3 + 2 = 5 can be rewritten as the subtraction problem 5 - 3 = 2 or 5 - 2 = 3.
