Calculate with the Basic Calculator -- bc

You can do simple command line calculations with the basic calculator, bc, such as add, subtract, multiply, division, modulus, sqrt, raise a number to a power, logarithms, exponential, compute sines, cosines, loops, functions, and more. Here are some really basic examples -- scale was used to represent precision. I have used the bc command while in the single user mode.
