Since the total of the divisors(excluding itself) is 7<8, it is a defective number. The sixth of the Fibonacci sequence, after 5 and before 13. It is the quantity of the twin primes 3 and 5. The first octagonal value. 8 is a Ulam, centered heptagonal and Leyland number. All amounts are divisible by 8 if and only if the result formed by its last three digits is. A refactorizable, being divisible by the count of its divisors. At the same time a highly totter and highly cototent quantity. It is the fourth term of the succession of Mian-Chowla. Any odd greater than or equal to 3, elevated to the square, to which subtract is subtracted 1 is divisible by 8 (example: 7²=49 49-1=48 divisible by 8). The sum of two squares, 8=2²+2². The sum of the digits of its cube: 8³=512, 5+1+2=8. The first 4-digit binary:1000. Part of the Pythagorean triples (6, 8, 10), (8, 15, 17). Eight is a repeated number in the positional numbering system based on 3 (22) and on the base 7 (11).
• The number 9 explained: 9 is odd and the square of 3. It is a composite, with the following divisors:1, 3, 9. Since the quantity of the divisors(excluding itself) is 4<9, it is a defective number. In mathematics nine is a perfect total, suitable and a Kaprekar figure. Any amount is divisible by 9 if and only if the quantity of its digits is. Being divisible by the count of its divisors, it is refactorizable. Each natural is the sum of at most 9 cubes. If any sum of the digits that compose it is subtracted from any natural, a multiple of 9 is obtained. The first odd square and the last single-digit quantity. In the binary system it is a palindrome. Part of the Pythagorean triples (9, 12, 15), (9, 40, 41). A repeated number in the positional numbering system based on 8. Nine is a Colombian digit in the numerical decimal system. If multiplied 9 always leads back to itself: 2×9=18 → 1+8=9, 3×9=27 → 2+7=9 in the same way if you add a number to 9, the result then refers to the initial digit: 7+9=16 → 1+6=7, 7+9+9=25 → 2+5=7, 7+9+9+9=34 → 3+4=7. If you put 111111111 in the square (ie 1 repeated 9 times) you get the palindrome 12345678987654321, also if you add all the numbers obtained: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 you get 81, and in turn 8 + 1 = 9.

## Number 89 Meaning In English Words

To write and remember the correct spelling of 89 you better learn the language rules for writing numbers in words.

In English numbers from 1 to 12 are unique words that you have to remember. Numbers from 13 to 19 end with 'teen' and have the same begginning as is their last number. Starting from twenty all tens end with 'ty'. Tens where the second number is bigger than 0 are written by using a hyphen and simply writing the last number.

For numbers bigger than 100, a 'and' is placed before the tens (in American English the 'and' is optional). For the number 100 itself, 'a' or 'one' must be used. But 'a' can only be at the beginning of a number. The same principle of 'a' and 'one' applies to the hundreds(such as 1000, 402000 and so on).

Thousands are separated by commas. As a rule, the numbers are written in the singular. The plural is only used in dozen, hundred, thousand, million, billion if they are not specified by another number.
