These tables consisted of a list of the first twenty multiples of a ... three. In this example, the number two is the base, and three is the exponent. [26] In general ...
14, 49, −21 and 0 are multiples of 7, whereas 3 and −6 are not. This is because there are integers that 7 may be multiplied by to reach the values of 14, 49, 0 and −21, while there are no such integers for 3 and −6.
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]
Cycles of the unit digit of multiples of integers ending in 1, 3, 7 and 9 (upper row), and 2, 4, 6 and 8 (lower row) on a telephone keypad. Figure 1 is used for multiples of 1, 3, 7, and 9. 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.
Positive numbers: Real numbers that are greater than zero.; Negative numbers: Real numbers that are less than zero.Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero.
26 is the smallest even number n such that both n + 1 and n − 1 are composite. With an aliquot sum of 16, within an aliquot sequence of five composite numbers (26,16,15,9,4,3,1,0) to the Prime in the 3-aliquot tree. 26 is the only integer that is one greater than a square (5 2 + 1) and one less than a cube (3 3 − 1).

The kindnesses multiply and the community starts to notice this kid. Things are really starting to improve and there's a really hopeful future. Anyway, >!the kid stands up to a bully and gets ...
26: It is divisible by 2 and by 13. [6] 156: it is divisible by 2 and by 13. Subtracting 5 times the last digit from 2 times the rest of the number gives a multiple of 26. (Works because 52 is divisible by 26.) 1,248 : (124 × 2) − (8 × 5) = 208 = 26 × 8. 27: Sum the digits in blocks of three from right to left. (Works because 999 is ...
