Calculating Complements (10's)




Recollect the concept of complements what we learned in our school times !!!!
We take a base number (Ex.10 or 100), and subtract the given number to find the complement. Same Concept with a different technique.

Just follow the formula (Subtract) All from Nine and the last from 10.

Take any number, for Ex. 675

(9-6)(9-7)(10-5)= 325 is the answer.

Is in it easy ? here we don't have to worry about the no. of base or the no. of digits in the given number... just apply the rule and get the results......
