Summary

Every Rust program starts at the main function

Inside the main function, you can do things like call println

The println macro lets us do interpolation to produce outputs

We can define variables that hold onto values using let

We can perform basic arithmetic using +, -, *, and /

Each value has a type, which says what kinds of things it can hold

1. A &str is the type of a string literal, like "Michael"

2. There are lots of different number types, but we’ll mostly use i32
