The Most Hardest Times Table of Nine Becomes Most Easiest Just By Manipulating With Zero to Nine Numbers

In our old school days, most of us hates table of nine at first look and feels the hardest table among first ten tables we started learning at the beginning of learning tables in our childhood.

One quick tip of manipulating zero to nine numbers to make table of nine the easiest one.

First let’s have one look at table of tine.
          9 × 01 = 09
          9 × 02 = 18
          9 × 03 = 27
          9 × 04 = 36
          9 × 05 = 45
          9 × 06 = 54
          9 × 07 = 63
          9 × 08 = 72
          9 × 09 = 81
          9 × 10 = 90

If you look at answers carefully you can notice that all right most digits of the answers are nothing but just the sequence of numbers from 0 to 9 and all left most digits of the answers are the sequence of numbers from 9 to 0.
          9 × 01 = 09 = 0 9
          9 × 02 = 18 = 1 8
          9 × 03 = 27 = 2 7
          9 × 04 = 36 = 3 6
          9 × 05 = 45 = 4 5
          9 × 06 = 54 = 5 4
          9 × 07 = 63 = 6 3
          9 × 08 = 72 = 7 2
          9 × 09 = 81 = 8 1
          9 × 10 = 90 = 9 0

One more interesting thing is that when you sum up the digits of any answer from table will always gives you nine, in this way you can cross verify the correction of your answer.
          9 × 01 = 09 = 0+9 = 9
          9 × 02 = 18 = 1+8 = 9
          9 × 03 = 27 = 2+7 = 9
          9 × 04 = 36 = 3+6 = 9
          9 × 05 = 45 = 4+5 = 9
          9 × 06 = 54 = 5+4 = 9
          9 × 07 = 63 = 6+3 = 9
          9 × 08 = 72 = 7+2 = 9
          9 × 09 = 81 = 8+1 = 9
          9 × 10 = 90 = 9+0 = 9

So now enjoy the table of nine.
