Multiples of 9 up to 100
There are 11 multiples of 9 from 1 to 100: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99.
From 9 to 81, the multiples of 9 run in a diagonal line from top right to bottom left: each one is one row down and one place to the left of the last. Then 90 and 99 start the line again.
Patterns that help
The last digits go 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and then repeat. Every digit from 0 to 9 appears once before the pattern repeats.
9 is odd, so its multiples go odd, even, odd, even: 9, 18, 27, 36.
A quick check: Add up the digits. If the total is a multiple of 9, so is the number. For 72, 7 + 2 = 9. For 378, 3 + 7 + 8 = 18, which is 9 × 2.
Building the list from facts you know: Work out 10 lots, then take one lot away: 9 × 8 is 80 − 8, which is 72.
