Here are some tips to help you type your problem into a text-box on this site:
The + key means plus, and - key means minus. * ([Shift]-[8]) means times and / means divide. 2+2/3*8 is "two plus two divided by 3 times 8."
Webmath always follows the correct "order of operations" on everything you type.
Webmath knows when to multiply. So if you have 2(x+1), you don't need to type it at 2*(x+1); type it like 2(x+1).
Fractions are typed using the slash, or / key as the fraction bar. So, "two-thirds" would be
typed as 2/3. "One-half" would be types as 1/2.
Exponents are typed using the caret, or ^ key ([Shift]-[6] on your keyboard). So, 2^{2} would be typed 2^2. x^{2} would be typed x^2. (x+5)^{2} would be typed (x+5)^2.
You can put a fraction in an exponent. x^{2/3} should be typed like x^(2/3).
With more complicated fractions you have to use parenthesis. For example if you typed x^2+1/x-5, you might think this means "the quantity 'x-squared plus 1' over the quantity 'x minus 5'." Actually, this site would correctly put 1/x as the only fraction. Instead, you should type it like this: (x^2+1)/(x-5).
Webmath DOES NOT know about constant like Pi (=3.1415...), and e (=2.718..). If you need these, you can just put them in directly as numbers. Or, you can put P in for Pi and E in for e. Webmath will carry these through in a problem, and you can see what happened at the very end.
