Chat with our AI personalities
Dividing any number by zero is undefined in mathematics. This is because division by zero would imply finding a number that, when multiplied by zero, gives the original number. However, this is not possible as any number multiplied by zero is always zero. Therefore, 19 divided by 0 is undefined.
No number can be divided by zero.
In theory the result is infinity, but there are no practical applications of the calculation.
