120 is . the factorial of 5, i.e., ! =.; the fifteenth triangular number, [2] as well as the sum of the first eight triangular numbers, making it also a tetrahedral number. 120 is the smallest number to appear six times in Pascal's triangle (as all triangular and tetragonal numbers appear in it).
To do this, he called the numbers up to a myriad myriad (10 8) "first numbers" and called 10 8 itself the "unit of the second numbers". Multiples of this unit then became the second numbers, up to this unit taken a myriad myriad times, 10 8 ·10 8 =10 16. This became the "unit of the third numbers", whose multiples were the third numbers, and ...
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
Figure 2 is used for the multiples of 2, 4, 6, and 8. These patterns can be used to memorize the multiples of any number from 0 to 10, except 5. As you would start on the number you are multiplying, when you multiply by 0, you stay on 0 (0 is external and so the arrows have no effect on 0, otherwise 0 is used as a link to create a perpetual cycle).
Each of these words translates to the American English or post-1974 British English word billion (10 9 in the short scale). The term billion originally meant 10 12 when introduced. [7] In long scale countries, milliard was defined to its current value of 10 9, leaving billion at its original 10 12 value and so on for the larger numbers. [7]
Typically, Ilocanos use native numbers for one through 10, and Spanish numbers for amounts of 10 and higher. Specific time is told using the Spanish system and numbers for hours and minutes, for example, Alas dos/A las dos (2 o'clock). For dates, cardinal Spanish numbers are the norm; for example, 12 (dose) ti Julio/Hulio (the twelfth of July).
Systematic generalizations of this basic definition define the multiplication of integers (including negative numbers), rational numbers (fractions), and real numbers. Multiplication can also be visualized as counting objects arranged in a rectangle (for whole numbers) or as finding the area of a rectangle whose sides have some given lengths.
It is the third (or second) dodecahedral number, [4] and the sum of the first seven triangular numbers (1, 3, 6, 10, 15, 21, 28), which makes it the seventh tetrahedral number. [5] The number of divisors of 84 is 12. [6] As no smaller number has more than 12 divisors, 84 is a largely composite number. [7]
