Functions are an integral path of being able to reuse code in other programs. A function is the named block of code, that performs the specific action. To paint the vivid picture, we want to add two numbers, for the volume of lab reagents. Simply type 100 plus 100, or 200 plus 100 This isn't a big deal, if we need to do this like five times or maybe 10 times. But what if we need to do these a 100, or a 1000 or a million times?
