SR-40 TEXAS INSTRUMENTS
The extremely rare SR-40 LCD (1981) calculator produced in Brazil is an interesting model, as at first glance it looks very similar to the European version of the TI-30 LCD. However, a few differences set it apart. One of the most noticeable differences concerns the keys: while the European TI-30 LCD features the **N!** (factorial) key, the Brazilian SR-40 LCD has the **x!** key, a detail that might reflect slight variations in functionality or target use.
