Answer:
To multiply a number with 9 we use the following trick:
The number×(10-1)
13680347×9=13680347×(10-1)= 136803470-13680347=123123123
35702369×9=35702369×(10-1)=357023690-35702369=321321321
25692359×9=25692359×(10-1)=256923590-25692359=231231231
These results repeat the digits 1,2 and 3 in a cyclic pattern.
