b^3 also sent me the maths code but I'm so lazy. It takes too much time. I type very slowly as well

Haha, I was hoping that I'd be able to show that it doesn't actually take too long for most things, for your post was just adding the LaTeX tags and then the code for the fractions really - which was writing \frac{16loge(5)}{loge(x)} instead of 16loge(5)/loge(x), or alternatively {16loge(5)} \over {loge(x)}. Yeah it looks a bit frightening at first, but it's pretty simple once you've used it 3 or 4 times.

For the superscripts and subscripts, you would have typed them out in the style required in the first place. You also get in the habit of typing things like log_e too. For stuff like integrals, matrices and more complex things, I can understand that it'd take a long time if you're not used it, that's fine.

For just regular algebra and fractions, though, I think it's easy enough to adapt to it.

Along the way you pick up on on little things like using \pi and \not{=} and \vec{a}, which you can look up a couple of times before you know how to do it, but that's not necessary for a lot of posts. It's really the fractions and not having to use excessive brackets in order to not be ambiguous where the advantage lies.

edit: By the way, my posts aren't really directed at you specifically, it's just something that's been on my mind for quite a while now.
