I have learned that 1 0 is infinity, why isnt it minus infinity? 92 The other comments are correct: 1 0 1 0 is undefined Similarly, the limit of 1 x 1 x as x x approaches 0 0 is also undefined However, if you take the limit of 1 x 1 x as x x approaches zero from the left or from the right, you get negative and positive infinity respectively
