# I am confused

$$\frac{1}{0}$$=$$∞$$

My teacher says this is undefined, while my calculator says this is true. Is this true or false?

You first need to know that infinity is not a number. It doesn't follow simple algebra. Infinity is largest term that we cannot approach. Infinity depends on one's point of view to define. · 5 months, 3 weeks ago

Your calculator will simply say whatever the programmers of said calculator told it to say for division by 0. Mathematically speaking though, division by 0 is undefined. · 6 months ago

@M K Then why does the limit of 1/x as x approaches 0 approach $$∞$$? · 6 months ago
