why it works?????
since you cannot divide by 0, \[\frac{100-100}{100-100}\] is not a number if you start with a false premise, you can prove anything you like think politics for example
@satellite73 i think it would be more lucid if you explain him premise because it takes this into philosophy of mathematics where it is compulsory to know what premise means ...rest it is an excellent answer for all of us because false premise can lead us to a right conclusion
