110 ÷ 5 = 22 (The result is the same as the original number divided by 5) If the last digit is 5. 85 (The original number) 8 5 (Take the last digit of the number, and check if it is 0 or 5) 8 5 (If it is 5, take the remaining digits, discarding the last) 8 × 2 = 16 (Multiply the result by 2) 16 + 1 = 17 (Add 1 to the result)
An orange that has been sliced into two halves. In mathematics, division by two or halving has also been called mediation or dimidiation. [1] The treatment of this as a different operation from multiplication and division by other numbers goes back to the ancient Egyptians, whose multiplication algorithm used division by two as one of its fundamental steps. [2]
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 ...
Two to the power of n, written as 2 n, is the number of values in which the bits in a binary word of length n can be set, where each bit is either of two values. A word, interpreted as representing an integer in a range starting at zero, referred to as an "unsigned integer", can represent values from 0 (000...000 2) to 2 n − 1 (111...111 2) inclusively.
The neat coincidence that 2 10 is nearly equal to 10 3 provides the basis of a technique of estimating larger powers of 2 in decimal notation. Using 2 10a+b ≈ 2 b 10 3a (or 2 a ≈2 a mod 10 10 floor(a/10) if "a" stands for the whole power) is fairly accurate for exponents up to about 100.
This 4 is then placed under and subtracted from the 5 to get the remainder, 1, which is placed under the 4 under the 5. Afterwards, the first as-yet unused digit in the dividend, in this case the first digit 0 after the 5, is copied directly underneath itself and next to the remainder 1, to form the number 10.
b) Divide N2 by 4 again, yielding quotient N3 and remainder B2. Place a second Bishop upon the dark square corresponding to B2 (0=a, 1=c, 2=e, 3=g). c) Divide N3 by 6, yielding quotient N4 and remainder Q. Place the Queen according to Q, where 0 is the first free square starting from a, 1 is the second, etc.
512 is a power of two: 2 9 (2 to the 9th power) [1] and the cube of 8: 8 3. [2] It is the eleventh Leyland number. [3] It is also the third Dudeney number. [4] It is a self number in base 12. [5] It is a harshad number in decimal. It is the cube of the sum of its digits in base 10. [6] It is the number of directed graphs on 3 labeled nodes. [7]
