In the text on division (see above), we learned that it is not possible to divide by 0, which is labeled an undefined number. But you can have zero (0) as your numerator. And any allowed fraction (one that doesn’t have a 0 in the denominator) that has 0 as its numerator will always be equal to zero (0). For example, 0/5 and 0/345 both equal 0.
