Calculators by task

Most people arrive at a calculator with a task, not a formula: work out what actually lands in my account, compare what two mobile-money networks charge, check what a loan really costs, convert a price in dollars. These eight groups follow those tasks, and a tool appears in more than one when it genuinely serves both — the SDL calculator is a salary tool and a business one.
