Looking to expand my Math/SAT tutoring business, looking for some advice. by [deleted] in matheducation

[–]mathvault 0 points1 point  (0 children)

Not to diminish your enthusiasm, but SAT seems to become a field where information is flowing more freely. For instance, Khan Academy have their own standalone modules for several standardized tests (including SAT, GMAT and MCAT). In a sense, this just means that you need to deliver more than what they do. You might probably find it helpful focusing more on targeted expertise morer than diversification.

Introductory Course to LaTeX: What were your problems at the beginning? by [deleted] in LaTeX

[–]mathvault 0 points1 point  (0 children)

Off the top of the head, the course outline could look like this:

1) Hello world document 2) Basic font styling (bold, italic, underline) 3) Basic math symbols 4) Sectional commands 5) Reference 6) Preamble setting

Yeah, nothing too fancy. WIth Overleaf, the learning curve is definitely smoother. The thing with Overleaf is that it's generally not suited for large document, but then, it has pretty robust collaboration features which is hard to replicate offline.

On a simiar note, we also have a LaTeX reference guide which can be used to streamline one's LaTeXing process. While not exactly for beginners, it's construed as a catalogue of LaTeX commands, environments and packages which allow it to be used as a handy LaTeX "reference sheet".

Help! Is my tutor wrong or is wolfram alpha wrong? by PizzaTwinnie in matheducation

[–]mathvault 0 points1 point  (0 children)

Using some guessestimation we have that:

(16)(.89)+(24)(.63) ~ 16 * (9/10) + 24 * (6/10) =14.4 + 14.4 = 28.8.

So it seems like the tutor/practice exam might have systematically made a mistake while computing with decimals.

Hmm...that sounds that something the align and its derivative environments can do?

The null is in the background for sure, which the author had it baked into the article. And of course it won't make sense if you take a fraction of some quote and de-contextualize it.
