I have learned that 1/0 is infinity, why isn’t it minus infinity?

My brother was teaching me the basics of mathematics and we had some confusion about the positive and negative behavior of Zero. After reading a few post on this we came to know that it depends on the context of its use.

Why do we take 1/0 as positive infinity rather than negative infinity (we come close to zero from negative axis)?


The other comments are correct: 10 is undefined. Similarly, the limit of 1x as x approaches 0 is also undefined. However, if you take the limit of 1x as x approaches zero from the left or from the right, you get negative and positive infinity respectively.
