Multiples of 9
Multiples of 9 are what you get when you multiply 9 by whole numbers. Common multiples of two numbers lead to the LCM.
Skip-counting keeps the last-digit rhythm of 9: the first ten multiples end in 9, 8, 7, 6, 5, 4, 3, 2, 1, 0. The first ten also pair to 99 in five pairs (9 + 90, 18 + 81, …) — the same numbers the multiplication table shows under other names. Because 9 is odd, consecutive multiples alternate odd and even: 9 is odd, 18 is even, 27 is odd again. The tenth multiple is the place-value shift: 90 is just 9 with a zero appended, since multiplying by ten always moves one place left. First common multiple with 2: 18, in row 2; with 3: 9 (row 1).
