How do I get parameters between activities?

Question

I am working on an app that has multiple tabs. In the first tab the user will enter values. In the other tabs it will display the results of calculations based off of those values.

Like in tab 1, the user will enter "3" and "2". In tab 2, the program will add them and display "5".

In tab 2 how do I access the ints "3" and "2"?

Thanks

The TabHost widget lets you design its tabs with or without individual activities. It does not look like there is a need to have separate activities when you switch tabs in your scenario. Why not use a single activity?
