For Teachers

(1/2x + ... = ?, Calculators that Crush Challenging Math Problems


[Equation with one unknown],Uravnenie s odnim neizvestnym., Digital ID 1692028, New York Public LibraryThe World Wide Web is a great source for online calculators. Some of these calculators are much more powerful than your typical desktop calculator. They show you not only the answer to your problem but also the step-by-step process used to get to that answer.

If a student is not sure how to do a math problem these calculators can help…but…there is often more than one way to solve a problem. A teacher may show a different method of solving a problem.

These calculators cover different subjects and work in different ways. Choose the one you like best. Calculators

Thank you so much for the useful resources you share each month!I find it difficult to locate things in the NYPL website. Finding your blog not only provides useful informaitonm, but brings me to a page where I can find so much more of what I really need and want! Hurray!

Thank You

I'm so glad you are finding my blogs useful :-)


I'm surprised you didn't mention WolframAlpha, the site from the guy behind Mathematica, that is intended to be able to solve any math problem you give it (along with doing many other things).
Great post.. Thanks for sharing...
