Maths is *hard*!

After explaining to a student, with various lessons and examples, that \[ \lim_{x \to 8} \frac{1}{x - 8} = \infty \] I tried to check if she really understood that, so I gave her a different example. This was the result: \[ \lim_{x \to 5} \frac{1}{x - 5} = ['5' rotated 90° to the left] \]
