Calculator project

Hi,
I am thinking of making a small calculator that will need to compute sine, cosine, tan and arctan, plus sqrt.· It will be a simple input using buttons and then·the result will be displayed on a 4 digit display.·
I am a newbie and have been going through the SX materials for the past year as time allows, so I need some help in setting the right path here.· I would love to use the SX, but it does not have the math functions.· So I am thinking that a different product needs to be used.· (maybee a math co-processor for the basic proof of concept so I can keep on SX-Bing?)
So I think the requirements are as follows:
Given these inputs is there a parallax product that I should use or is there some other product I need to look at?
Mark.

12-25-07 Got SX Lite Kit Plus for Christmas
12-27-07 Bought LED's and other components
12-29-07 Realized that none of my wal-warts work with board
1-2-08 Bought power supply and turned on·board, but realized the A shell sub-D connector on laptop is actually 15 pins and not serial.
1-3-08 Decided to use old laptop with a serial sub-d, that barely meets the minimum sk-key requirements.· Got LED to BLINK!!!!!!

So I think the requirements are as follows:
- able to take 3-5 input buttons
- able to drive a 4 digit display
- needs to do the math indicated above
- possibly be able to store input data (later on addition)
Given these inputs is there a parallax product that I should use or is there some other product I need to look at?
