ZEROS IN SUBTRACTIONZero is called the amazing number. Reason of this ‘amazing’ is that no matter whether the number zero is multiplied, added or subtracted from zero the answer is still zero. And whenever zero is subtracted from any other number the answer is still the number.
7 – o = 7 12 – 0 = 12
142 – 0 = 142So, when you subtract Zero from a number the difference is that number.
7 – 7 = 023 – 23 = 0
145 – 145 = 0When you subtract a number from itself, the difference is Zero.
