Dermit Dad ,

Your math is off

267.46+176.97 = 444.4299999999
Really?

And where is the +/- button?
Could you please add a unit conversion calculator as well?

The calculator I was looking for.

This is the calculator I was looking for. I recently subscribed to the ‘removed ads’ version because this is the one calculator app that had the features I was looking for. For example, I can easily see the last inputs because there is a history panel which you can scroll up and down with the swipe of a finger. I also enjoy the ‘last’ button feature that allows me to do calculations in where I can use my previous calculated sum—multiply/subtract/etc it by an even prior sum, easily accessible via the history feed. Thanks.

Solid Basic Calculator

This let’s you fully type out multi-expression math problems. It can’t do anything too fancy, it’s just a solid replacement for the basic calculator.

Also, if you close the app, the previous expressions stay in your history (I’m not sure about restarting the phone though).
