Summary

Being able to work with all sorts of data is crucial to your success as a C# developer. Just as you need to understand basic math to function in society, you need to be able to perform basic math in code to write even the simplest of applications. Knowing the arithmetic operators and understanding the order of operator precedence will take you a long way in performing math using C# code.

Boolean logic is a special form of evaluation used by C# to evaluate simple and complex expressions alike down to a value of true or false. In the following hours, you'll learn how to create loops and how to perform decisions in code. What you learned here about Boolean logic is critical to your success with loops and decision structures; you'll use Boolean logic perhaps even more often than you'll perform arithmetic.

Manipulating strings and dates each takes special considerations. In this hour, you learned how to work with both types of data to extract portions of values and to add pieces of data together to form a new whole. String manipulation is pretty straightforward, and you'll get the hang of it soon enough as you start to use some of the string functions. Date manipulation, on the other hand, can be a bit tricky. Even experienced developers need to refer to the online help at times. You learned the basics in this hour, but don't be afraid to experiment on your own.
