prime factoring, oddly enough, is simply dividing by primes, anyhow, without much adieu.
36 = 2 * 2 * 3 * 3.
but anyway, prime factoring, is dividing by first 2, till you can't, then 3 till you can't, then 5 till you can't, and so on, and that plucks out all possible factors on any number.
2.161616 = 2.161616/1 =21. 61616/10 = 216.1616/100 = 2161.616/1,000
= 21616.16/10,000 = 216161.6/100,000 = 2161616/1,000,000
As a mixed number = 2(161616/100,000)
|-11+8|=|-3|=3. Plug in f(-11)
Início = 6 h
9 x 6 = 54
6:54 passou o nono ônibus
próximo ônibus = 6:54 + 9 = 7:03
próximo = 7:03 + 9 = 7:12
próximo = 7:12 + 9 = 7:21
você chegou às 7:16 e vai esperar 21-16 = 5 minutos
