MULTIPLICATION BY 9 : Step I: Subtract the righthand figure of the long number from 10. This gives the righthandIfirgute of the answer.Step II: Taking The next digit from right, subtract it from 9 and add the neighbour on its right. Step III: At the last step, whentou are under the zero in front of the long number, subtract one from the neighbour and use that as the lefthand figure of the answer. Ex 1 : 8576 X 9 = ?
Step I. Subtract the 6 of 8576 from 10, and we have 4 of the answer. Another Trick Step I : Put a zero at the right end of the number; ie, write 85760 for 8576. Step II: Subtract the original number from that number. Like 85760  8576 = 77184
