<em>Comment on the use of a calculator</em>
Many calculators assume that a percentage is to be multiplied by something. If you type this expression into the Google calculator, it will take the % symbol to be an indicator that modulo arithmetic is desired. (It will compute .25 mod -.125 = 0.) So, you need to be aware of how your calculator handles "%". It may be best to do the conversion to decimal before you present the problem to a calculator.
