|Type:||Programmable scientific calculator|
The HP 33E has a twin brother, the HP 33C. The difference between
these two calculators is that this one (the 33E) doesn't have
constant memory, whilst the 33C does. This calculator is quite a
basic programmable calculator (conform HP's standards), quite
similar to the earlier HP
25. It does have some extra functions however.
