M3 MasterMindMath > Subtraction > Subtraction from Base Number > Unequal number of digits
2. Base Number is : 1 Followed By 0 (As in 10, 100, 1000…)
Subtracting when the Number of Digits in Second No. is
NOT The SAME
as the Number of Zero’s in Base No.
10000
824 There are 3 Digits in the Second Number
There are 4 Zeros in the Base Number

There are 3 Zeros in Base No.,
while only 2 Digits in Second
No.
By ADDING ZERO, now there
are 3 Zeros in Base No. and
3 Digits in Second No.
