Numbers Used In Spelling 90 Roman Numerals

  • 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.
  • The number 0 explained: 0 is the only real figure that is neither positive nor negative. Sometimes it is included in natural numbers where it can be considered the only natural in addition to the one to be neither first nor composed, as well as the minimum of natural numbers(that is, no natural digit precedes the 0). In an oriented line (which makes a point on the straight line correspond to each real number, preserving also the relation of order), the 0 coincides conventionally with the origin. Since it can be written in the form 2k, with con k integer, 0 is called even. It is both a figure and a numeral. In set theory, the zero is the cardinality of the empty set. In fact, in certain axiomatic mathematical developments derived from set theories, zero is defined as the empty set. In geometry, the size of a point is 0. Zero is the identity element of an additive group or additive identity in a ring.
