Document Summary

Computer scientists model and analyze problems, design solutions and verify solutions. The three steps of computer science: think of a solution, translate into a program (coding, check if it"s correct (testing and debugging, computer science is the science of algorithms. An algorithm is simply a sequence of steps that tells you how to solve a problem. Converting between decimal and binary: day to day, we use base 10 (decimal) when we refer to numbers. However a computer is a series of wires that either have current flowing through them, or do not: an easier way to think of it: light switches that are on or off. So: computers talk in base 2 (binary), and our languages to code them need to be written as such: binary only contains 2 numbers: 0 = off: hence we must be able to understand both notations and convert between them. This is equivalent to 5000 + 700 + 60 + 3.
