Where is the calculator from 10.04?

view story

http://askubuntu.com – The default calculator from Ubuntu 10.04 was perfect. It was simple, yet powerful. It had memory locations and when you switched between Hexadecimal and Decimal the number in the display changed to represent the value in the new base. The Ubuntu 12.04 default calculator does not have a memory function, and the display does not change when you change base. Is there a way to install the old calculator application, or is there an alternative that is similar? (HowTos)
