I just want to know if 1÷1 is 1, what is0÷0?

division of anything by zero is undefined.

0/0 is not zero. It is undefined.

When it comes to the division of numbers, it's essential to understand the concept of division by zero. Dividing any number by zero is undefined in mathematics, which means it does not have a specific value.

Let's look at the case of 1 ÷ 1. When dividing 1 by 1, we get a result of 1 because any number divided by itself will always equal 1. So, 1 ÷ 1 = 1.

Now, let's consider 0 ÷ 0. If we attempt to divide zero by zero, we encounter a problem. Dividing zero objects into zero equal groups results in ambiguity because we are not sure how many objects should be in each group. As a result, the value of 0 ÷ 0 is considered undefined in mathematics. It means that there is no specific number that we can assign to this division.

So, in summary, while 1 ÷ 1 equals 1, the expression 0 ÷ 0 is undefined.
