## Incrementing

### Video Transcript

In this section, we're going to learn about incrementing. Incrementing is when you increase the value of a variable by some amount. We actually saw an example of this in action in the previous section:
```count = 0
command = ""
while command != "quit":
command = input("Enter a command: ")
count = count + 1
print(f"The value of count is {count}.")
```
Here, the variable `count` is initialized to 0, and on every iteration of the loop, `count`'s value is increased by 1 using the line `count = count + 1`. If `count`'s value is 0, then this line tells the computer to take the current value of `count` (which is 0), add 1 (to get 1), and save it back in the variable. So now, instead of having a value of 0, `count` has a value of 1. On the next iteration, the computer again takes the value of `count` (which is now 1), adds 1 (to get 2), and saves it back in the variable again. This way, the value of `count` gets higher and higher on every iteration of the loop.
We can do this not just with addition, but with any math expression we want, and instead of increasing by 1, it will update the variable according to the expression:
```count = 0
command = ""
while command != "quit":
command = input("Enter a command: ")
count = count * -5 / 2 - 1
print(f"The value of count is {count}.")
```
