Canon F-720i Scientific Calculator

Canon calculators are not as popular as the ubiquitous Casio scientific calculators. However, this Canon model is very similar in look and feel to its Casio "brothers". It has a two line display - the top [smaller sized] dot matrix alphanumeric display shows mathematical symbols [operators, brackets, square root, sin/cos/tan, etc] and numbers; and the lower seven segment 12 number display shows the answers. The Casio ones have larger displays that make them easier to read; but other than that there's little to choose between the two. Both offer the same range of mathematical, trigonometric and statistical functions. The Canon also comes with good instructions in abour 10 languages! I recommend the Canon if you don't mind the smaller display size.
