Other uses for fractions are to represent ratios and division. [1] Thus the fraction 3 4 can also be used to represent the ratio 3:4 (the ratio of the part to the whole), and the division 3 ÷ 4 (three divided by four).
Division is one of the four basic operations of arithmetic. The other operations are addition, subtraction, and multiplication. What is being divided is called the dividend, which is divided by the divisor, and the result is called the quotient. At an elementary level the division of two natural numbers is, among other possible interpretations ...
Collatz conjecture Unsolved problem in mathematics: For even numbers, divide by 2; For odd numbers, multiply by 3 and add 1.
The series 1 4 + 1 16 + 1 64 + 1 256 + ⋯ lends itself to some particularly simple visual demonstrations because a square and a triangle both divide into four similar pieces, each of which contains 1 4 the area of the original.
The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4; [2] [3] this is because 100 is divisible by 4 and so adding hundreds, thousands, etc. is simply adding another number that is divisible by 4.
In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 .
1/2 + 1/4 + 1/8 + 1/16 + ⋯. First six summands drawn as portions of a square. The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1.
For a quick understanding of numbers like 1/2.3", see § Table of sensor formats and sizes. For broader coverage of this topic, see Image sensor. In digital photography, the image sensor format is the shape and size of the image sensor . The image sensor format of a digital camera determines the angle of view of a particular lens when used with ...
