It's a tongue twister for your brain.
New update works!!!!!!
If you are trying to get your children to learn their multiplication tables, addition, division or subtraction, this is the app for you. This app is really fun and children love to compete with one another. I even started playing against my son, he can now multiply 2 by 2 digits mentally!!
Perfect math reference app for all level math
Love this app! Really helps in AP Calc class.
Excellent source of information!
Very complete and each upgrade gets better and better.

Cutest and the only one that makes the choice intuitive..... Well who can compete with someone who wants to do his or her best for a child ha?! May children inspire us all every day!
This is by far the best calculator (if you can call it that) app on the iTunes app store (as of the beginning of 2009)- it has a featureset comparable to that of an advanced graphing calculator, like a TI-89, but with the benefit of a touch-screen interface and full-color graphics (which are especially nice for 3D plotting). SpaceTime also performs both numeric and symbolic algebra and calculus (including some advanced functions) and supports scripting. If you've used software like Maple or Mathematica, SpaceTime works in a similar function- not quite as feature-rich, but far more than you might expect from a handheld device.
At a glance I have so much information. I absolutely love it. Well done designers.
I was blown away by this app. When I first tried it and the tutorial came up, my first instinct was to skip past it. Then I started... Blown away. This calculator has everything and more. It is so logical for those who always wondered why calculators are sometimes so archaic. Forget copy and paste. Then I got to the graphing.... A must have period!
