Pattern to Remember Times Table of Three


Now let’s have a look on the table of three.
Here is the table of three as given in textbooks etc.
          3 × 01 = 03
          3 × 02 = 06
          3 × 03 = 09
          3 × 04 = 12
          3 × 05 = 15
          3 × 06 = 18
          3 × 07 = 21
          3 × 08 = 24
          3 × 09 = 27
          3 × 10 = 30
If you note right most digit it’s just sequence of zero to three repeating each number three times except three.
          3 × 01 = 0 3
          3 × 02 = 0 6
          3 × 03 = 0 9
          3 × 04 = 1 2
          3 × 05 = 1 5
          3 × 06 = 1 8
          3 × 07 = 2 1
          3 × 08 = 2 4
          3 × 09 = 2 7
          3 × 10 = 3 0
Left most digits are in the pattern 3, 6, 9, 2, 5, 8, 1, 4, 7 and 0.
Easy Trick to build this pattern
Simply write 3, 2 and 1.
Get next 2 digits of pattern by adding 3 and add them after 3, 2 and 1
So you will get 3, 6, 9, 2, 5, 8, 1, 4 and 7.
Finally put zero at the end.
          3 × 01 = 0 3
          3 × 02 = 0 6
          3 × 03 = 0 9
          3 × 04 = 1 2
          3 × 05 = 1 5
          3 × 06 = 1 8
          3 × 07 = 2 1
          3 × 08 = 2 4
          3 × 09 = 2 7
          3 × 10 = 3 0
Combining all above easily remember the times table of three.
