Our Review: Nice expression calculator - unfortunately not algebra supporting, but very easy to use nonetheless. 1st Calculator has one feature above all other calculators: skins. Not something common to this type of software, but excellent in terms of keeping things both interesting and accessible. 1st Calculator comes with a unit conversion table and a customisable list of constants. It calculates sums (especially trigonometric functions) very well - which makes 1st Calculator a very cool idea - and a great calculator.
