  2. Divisibility rule - Wikipedia

    en.wikipedia.org/wiki/Divisibility_rule

    The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4; [2][3] this is because 100 is divisible by 4 and so adding hundreds, thousands, etc. is simply adding another number that is divisible by 4.

  3. Determining the Outcome of a Match (association football)

    Most codes of football from before 1863 provided only one means of scoring (typically called the "goal", although Harrow football used the word "base"). [7] The two major exceptions (the Eton field game and Sheffield rules, which borrowed the concept from Eton) both used the "rouge" (a touchdown, somewhat similar to a try in today's rugby) as a tie-breaker.

  4. Division (mathematics) - Wikipedia

    This is denoted as 20 / 5 = 4, or ⁠ 20 / 5 ⁠ = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 / 3 leaves a remainder of 1, as 10 is not a multiple of 3.

    For example, if a team's season record is 30 wins and 20 losses, the winning percentage would be 60% or 0.600: % = % If a team's season record is 30–15–5 (i.e. it has won thirty games, lost fifteen and tied five times), and if the five tie games are counted as 2 1 ⁄ 2 wins, then the team has an adjusted record of 32 1 ⁄ 2 wins, resulting in a 65% or .650 winning percentage for the ...

  8. Sylver coinage - Wikipedia

    If an ender exists, it is always the largest number that can still be played. For instance, after the moves (4,5), the largest number that can still be played is 11. Playing 11 cannot rule out any smaller numbers, but playing any of the smaller available numbers (1, 2, 3, 6, or 7) would rule out playing 11, so 11 is an ender.
