Calculators for the small sums in daily life
A phone calculator is fine for adding two numbers, but it gets awkward the moment you need a formula. How much is 35 percent off with an extra 10 percent at the till? What is the monthly payment on a car loan? Exactly how old is someone born on 29 February? These calculators do the formula for you and show the answer in plain words.
