This is fairly straightforward. This is a list of symbols to use when presenting an equation (as the topic indicates). Beside each symbol, I will provide a brief explanation. If you cannot understand this list when asking for help, provide the question in as best a format as you are able (scan it and post an image if you can). I can understand most methods of presenting equations, but you never know when someone'll utterly baffle me...
+, -, <, >, and = - These all will be used in this guild for the same purposes as outside the guild. Addition, subtraction, less than, greater than, and equal to, respectively.
* - This symbol will be used for multiplication. This is the equivalent of what most grade school math books use 'x' for. So why am I using the '*' instead of 'x'? Because once you get into higher levels of math, 'x' is a variable, and I wish to avoid confusion as soon as possible. 2*3 = 2 times 3
/ - This symbol will be used for division. The grade school equivalent (a line with a dot above and below) is not found within most fonts. 1/2 = 1 divided by 2
^ - This symbol will be used for powers. If it is a square, for example, it will be ^2 (x^2 is x squared). When having a string of digits in the power, try to put the entire power within parenthesis (x^(1/2) is x to the one-half, or the square-root of x).
Letters - Aside from dealing with the algebraic sine, cosine, tangent, secant, cosecant, and cotangent (to be presented as sin, cos, tan, sec, csc, and cot, respectively), letters will be used for variables. (A variable is some value in the equation that is undetermined by the equation. Variables can be substituted for any number, but, for the most part, a variable's value is what one uses math to find.)
More to be added as needed.

When dealing with complex equations (anything dealing with multiple values that interact):
(), [], {} - When there's a string of variables combined apart from the rest, put them within one of these, () being the outermost, [] being the second most in, etc. It will be largely uncommon to make use of {}. Innermost is usually dealt with first (except in some cases of simplification), then work outward.
Example
2(x-3) + 4 = 9 means that x-3 is set apart from the rest, being its own value. This is multiplied by 2, and then added to the 4 to equal 9.
(Numerator)/(Denominator) - Straightforward. Whatever's in the numerator goes in parenthesis, and the same for the denominator.
Example(s)
(4-3)/2 means 4 minus 3 and then finish the equation.
2/(5-1) means that you subtract the one from the five and then finish the equation.
(7-4)/(9-5) As above, you solve what's inside the parenthesis (7-4) and (9-5) and then divide.
For multiplication instead of division, simply substitute * for / to give.
