In terms of partition, 20 / 5 means the size of each of 5 parts into which a set of size 20 is divided. For example, 20 apples divide into five groups of four apples, meaning that "twenty divided by five is equal to four". This is denoted as 20 / 5 = 4, or 20 / 5 = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is ...
d() is the number of positive divisors of n, including 1 and n itself; σ() is the sum of the positive divisors of n, including 1 and n itselfs() is the sum of the proper divisors of n, including 1 but not n itself; that is, s(n) = σ(n) − n
The result is the same as the result of 125 divided by 5 (125/5=25). Example. If the last digit is 0. 110 (The original number) 11 0 (Take the last digit of the number, and check if it is 0 or 5) 11 0 (If it is 0, take the remaining digits, discarding the last) 11 × 2 = 22 (Multiply the result by 2)
Depending on context (i.e. language, culture, region, ...) some large numbers have names that allow for describing large quantities in a textual form; not mathematical.For very large values, the text is generally shorter than a decimal numeric representation although longer than scientific notation.
1331 = 11 3, centered heptagonal number, [69] forms a Ruth–Aaron pair with 1330 under second definition. This is the only non-trivial cube of the form x 2 + x − 1, for x = 36. 1332 = pronic number [51] 1333 = 37 2 - 37 + 1 = H 37 (the 37th Hogben number) [165] 1334 = maximal number of regions the plane is divided into by drawing 37 circles ...
Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
