Easy way to remember...
(1) the digits in the multiples of 9 also equal 9 when added together such as 18 (1+8=9) and 45 (4+5=9).
(2) multiples of 9 less than 100 'reverse' half way thru (09 & 90, 18 & 81, 27 & 72, 36 & 63, etc.)
(3) start with 09 and add 1 to the tens column and subtract 1 from the ones column. (09, 18, 27, 36, 45, etc)

figure it out by multiplying 9 by integers until you go over 100

Surely this is not tough for you! It takes longer to post it than to write them down.
