This chapter covered some of the critical features of the Ruby language. We walked through the arithmetic operators and the order of operations for arithmetic functions in Ruby. These operators will allow you to perform every combination of computational calculation in your program. We also analyzed the difference between integers and decimals (also referred to as floats), which may not seem like a critical topic; however, an entire NASA rocket was lost due to choosing the incorrect numerical data type, resulting in a loss of millions of dollars!
In the next chapter, we're going to start diving into Ruby methods.
