For several years I have been looking for a free computer calculator to use in maths lessons. It needed to have a clear, large display so that I could use it for whole class teaching. Maybe there is one out there, but I could not find it! At last I found out how to edit javascript sufficiently to create what I was looking for.
I used a free javascript calculator from The JavaScript Source and edited the display so that it would produce the largest display practicable on a computer screen using the 800x600 mode. I have also created a version for displays in 1024x768 mode.
The calculator has been designed to work using Internet Explorer version 5 or version 6. It may not display correctly in other web browsers. It also needs javascript to be enabled.
The web page can be downloaded and saved onto your computer to be used off-line.
