triangular number: a number which can be represented as an equilateral triangle of dots, and is the sum of all the consecutive numbers up to its largest prime factor – it can also be calculated as n(n + 1) ⁄ 2, e.g. 15 = 1 + 2 + 3 + 4 + 5 = 5 (5 + 1) ⁄ 2.
What is quaternions in math?
quaternions: a number system that extends complex numbers to four dimensions (so that an object is described by a real number and three complex numbers, all mutually perpendicular to each other), which can be used to represent a three-dimensional rotation by just an angle and a vector.
What is composite number?
composite number: a number with at least one other factor besides itself and one, i .e. not a prime number. congruence: two geometrical figures are congruent to one another if they have the same size and shape, and so one can be transformed into the other by a combination of translation, rotation and reflection.
What are cardinal numbers?
cardinal numbers: numbers used to measure the cardinality or size (but not the order) of sets – the cardinality of a finite set is just a natural number indicating the number of elements in the set; the sizes of infinite sets are described by transfinite cardinal numbers, 0 (aleph-null), 1 (aleph-one), etc.
How to find the mean of a number?
Mean is a mathematical term for the concept commonly defined as "average." The mean is determined by adding all the numbers in a list and then dividing the sum by the number of numbers in the list.
What is derivative in math?
Derivatives are models that are used to show rates of change. They can be geometrical, like the slope of a curve, or physical models, which are drawn out in mathematical terms comprising numbers, letters, and symbols.
Why do mathematicians use logarithms?
Mathematicians used logarithms to determine the power to which a base or fixed number has to be raised to get to a given number. Math is Fun defines it simply as "How many of this number do we multiply to get that number?"
What is distribution in math?
Distribution is an algebraic term that defines the act of spreading terms out equally. Terms are variables or numbers joined by division and/or multiplication. They're distributed by multiplying terms inside of parenthesis with terms outside of the parenthesis.
What is integral in calculus?
Along with derivatives, integrals are the fundamental objects of calculus. A shortcut method of adding slices to determine a whole, integrals can be used to find many central points, volumes, and areas.

What is the symbol for almost equals?
The “≈” symbol is called an almost-equals sign. The fields of math and science tend to borrow a lot of letters from the Greek alphabet as commonplace symbols, and English tends to put a twist on the pronunciation of these letters.
What is an imaginary number?
An imaginary number is the result of taking the square root of a negative number. When reading an imaginary number aloud, simply pronounce the letter “i” as it is. 2i is pronounced “two i,” 3i is “three i,” etc.
What is the top number of a fraction called?
One divided by three equals a third. In a fraction, the top number is called the numerator and the bottom number is called the denominator. When saying fractions out loud, we usually treat the denominator like an ordinal number. That means ⅓ is pronounced “a third,” ¼ is pronounced “a fourth,” etc.
How many times does a cubed number equal a power of three?
Three cubed equals twenty-seven. Three to the third equals twenty-seven. Three to the power of three equals twenty-seven. An exponent is when you take a number and multiply it by itself a certain number of times, an operation called exponentiation. In other words, you take one number to the power of another number.
What is an improper fraction?
An improper fraction is a combination of a whole number ( integer) and a fraction and involves the use of the word “and.”. So 1½ would be one and a half, 2¾ would be two and three-fourths, etc. As stated before, decimals can occasionally be stated as an improper fraction.
What is the equal sign?
Usually, we say that one expression equals another, and the “=” symbol is fittingly called an equals sign. Though it is fairly common in English to say the word “equals,” it is also fine to use the singular “is.” For example, two plus three is five. Any mathematical statement involving an equals sign is called an equation.
What is the sign for adding numbers?
When saying the equation out loud, we use the w or d “ plus ,” and the “ + ” symbol is called a plus sign. The result of an addition equation is called a sum.
