Do you understand the math in an everyday problem? This could be as simple as how to calculate how much paint is needed for a room, how much mulch goes on a garden or how to calculate something complex in chemistry, vector math, statistics, astronomy or physics. Ask yourself, what do YOU know how to do that others don't?

With your knowledge, you can use a FREE vCalc account to build and share a useful online calculator that is free to the world. Look at how many items have been created and made available free above. That's over 15,000 calculator tools and growing. The vCalc Platform let's you build several classes of calculator objects to share your knowledge with the world.

**Calculators**: These are bundles of calculating functions (equations) and constants on one page. (e.g., Tiny House Material Calculator)**Equations**: These are single function calculator pages (e.g., Dollars per Gallon from Canadian Dollars per Liter)**Constants**: These are data item that require no user input to see the value of something. It can be as simple as a math constant (e.g., π = 3.14159...) or something useful in everyday life (e.g., the volume of play sand in a 50lb bag = 0.5 cubic feet). And yes, they can have very useful units.**Data-set**: These are tables of information that can be used in equations and constants. (e.g., Current Price of Corn)**Collections**: These are simplified bundles of calculating functions and constants that are great for articles, books and other groupings of information. (e.g., Calories Burned Doing Outdoor Activities)

SIGN UP for a free vCalc account and start creating powerful tools and information that is shared with the world. One you do, go to vCalc's Help Pages for step by step instructions on creating these helpful items.

Inside these objects, you can develop a user interface to receive inputs, specify what units apply to them, and then program powerful formulas and algorithms. You can use the descriptive WIKI page for each token to provide information, graphics and images, and pop-up tools for calculators on the fly. You can provide links to related information inside and outside of vCalc to help your users solve their problems. You can combine multiple functions in sequences of calculations that let the end user solve complex problems.

In short, vCalc has provided an ever increasing suite of capabilities in the vCalc Platform to let people like you, who know how to do complex things, to build calculating tools for the world.

Make the world a better place. Share what you know in a useful calculator page, and if you run into trouble, message us at vCalc using the **Not finding what you're looking for? Let us Help** bar and we will be happy to help.

On behalf of the people your knowledge will help, thank you.
