With its retro looks and nice colours, this calculator from Urban Outfitters seems both a pretty and helpful way to tackle your sums.
However, order the calculator online and you might be in for a bit of a shock when it shows up: it's actually a supersized standard calculator and its length is a massive 22cm long! Its size will obviously make it less easy to loose it under a mountain of paperwork.
Admittedly this gimmick isn't to everyone's tastes but if you like your 1970s-style at twenty-first century sizes, the calculator costs £15.
