0Multiply by 9's
Steps :
Step 1. Subtract the given multiplicand value by 1.
Step 2. Find the complement of multiplicand (Base value - Multiplicand value).
Step 3. Find the digit difference by subtracting multiplicand digit with multiplier digit. Assign (n).
Step 4. Start Step 1 value, next append step 3 (n) number of 9's and Step 2 value.
Example: 45 x 999 (Multiplicand Digits Less than Multiplier Digits)
Step 1 : 45 -1 = 44
Step 2 : Complement of 45 is 55 (that is 100 - 45)
Step 3 : Number of digit Difference from multiplier and multiplicand n = 3-2 = 1
Step 4 : 44955 (Its a final answer)
