Step 2: Add first repetitive number two times and multiply by the second repeated numeral. The factors/divisors of a number N, less the number itself, are referred to as the aliquot parts, aliquot divisors, or proper divisors, of the number.) ≫. 5. The abundant numbers below 100 are 20, 24, 30, 36, 40, 42, 48, 54, 56, 60, 66, 70, 72, 78, 80, 84, 88, 90 and 96. It can be shown that every ordered field contains, as a subset, an isomorphic copy of the rational numbers-- i.e., a set that is identical to the rational numbers in all its arithmetic operations; it may differ only in the names of some things, via a change in labeling. A few years before he died, aged 95 in 2010, I interviewed Martin Gardner at his home in Norman, Oklahoma. 7 - 7/7. The number of ordered arrangements of r objects taken from n unlike objects is: n P r = n! Example: For n = 6, (n2 - n + 1) = 31 and 31 + 33 + 35 + 37 + 39 + 41 = 216 = 63. Birthdays, ages, height, weight, dimensions, addresses, telephone numbers, license plate numbers, credit card numbers, PIN numbers, bank account numbers, radio/TV station numbers, time, dates, years, directions, wake up times, sports scores, prices, accounting, sequences/series of numbers, magic squares, polygonal numbers, factors, squares, cubes, Fibonacci numbers, perfect, deficient, and abundant numbers, and the list goes on ad infinitum. 5 6. Monomial : An algebraic expression made up of one term. See the textbook's discussion of “distinguishable objects and indistinguishable boxes” on p. 337, or look up Stirling Numbers of the second kind . Follow 93 views (last 30 days) Show older comments. Fractional Numbers - any number expressible by the quotient of two numbers as in a/b, "b" greater than 1, where "a" is called the numerator and "b" is called the denominator. The sum of the squares of the first seven prime numbers is 666. One of the first cryptarithms came into being in 1924 in the form of an addition problem the words being intended to represent a student's letter from college to the parents.
