Interesting Number Pattern ----> 18

Notice this pattern

13 * 13 = 169. Now sum up the digits as follows (01 + 69 = 70)

Reverse 13

31 * 31 = 961. Now sum up the digits again (09 + 61 = 70)

Now multiply 13 * 31 = 403. Sum up the digits again (04+03 = 07)

07 is the reverse of 70 :)

Try for 14

14 * 14 = 196 (01+96 = 97)

41 * 41 = 1681 (16 + 81 = 97)

14 * 41 = 574 (05 + 74 = 79)

79 is the reverse of 97 :)

There are more patterns and examples this way...
