Mikey B: Have downloaded several calculators on my iPhone over the years, not found one yet that does exactly what I want it to do, ie multiple keystrokes within the same calculation for vat etc, add or subtract percentages, also without having to pay extra to get rid of those pesky annoying adverts, and then I spotted this old friend, which is a smaller portable version of my reliable desktop Casio. Perfect, just like the one I used for school all those years ago, does exactly what I want, should have replaced it years ago.

The Casio SL300SV keyboard is ergonomically laid-out, intelligently integrating the most useful everyday functions whilst avoiding being overly 'scientific.' The attached hardcover folds over like a wallet, protecting the calculator from dings or scuffs. Though pocket-sized, the SL300SV boasts a large eight-digit LCD display (16-digit approximations), 3-key independent memory, as well as keys for percent, square root, sign change, profit margin % key, 4 constants (k) for +,-,x,÷, together with a key-rollover buffer. It automatically turns itself off when not in use, and the dual-power 'Solar Plus' operating system switches automatically from solar energy to battery power if the lighting changes. It takes me back to the late 1970's, when in my late teens I attended a junior engineering technician course at college. Happily then, the SL300SV inherits the distinctive 'look and feel' that helped to establish Casio as an acknowledged 'standard' in the global calculator market. Historically, in 1957 the Kashio brothers invented the first electronic calculator with their Casio Model 14-A. Mind you, 'back in...
