The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations with base-ten numbers. Many educators believe it is necessary to memorize the table up 9 multiply by 9. 



Number Relation in table 9 :-

There is a relation between the digits of all numbers in Multiplication Table of 9
Please see this relation;

9*1=09   where   0+9=9
9*2=18    where   1+8=9
9*3=27    where   2+7=9
9*4=36    where   3+6=9
9*5=45    where   4+5=9
9*6=54    where   5+4=9
9*7=63     where   6+3=9
9*8=72     where   7+2=9
9*9=81     where   8+1=9
9*10=90   where   9+0=9

It proves that every number of multiplication table of 9 when added to make a single number then this number is also 9.
