# Useful Math Tools Available Online

Personally, I’m dealing with math problems of all sorts everyday. One minor mistake with signs would give anyone a huge headache. Let’s say you are almost done with your solution. And when you compared the correct answer with what you have, you can’t figure out where you answered wrong.

I have a good news. There are many tools on the web that may help you deal with your doubts. Here are just few tools and websites that would definitely leave you amazed.

• #### Symbolab

You may use Desmos as your graphing calculator, especially if you cannot afford physical graphing calculators. Graphing several functions at the same time using Desmos is also possible. You may identify the functions using different colors. There is also an option to get the table of x and y coordinates given the function. Desmos is especially useful for me as well when scientific calculator is not available. You may also share the graph that you have made using Desmos to your friends. As far as I know, Desmos is totally free! ### Other Math Tools that are Worth Checking • Wolfram Alpha • This is also a free access tool not just for math, but even for other subjects.
