Nesting Function Calls

Just like we can nest arithmetic expressions and use variable names with operators, like in (1 + 2) * 4 or (number_of_tas * 2) we can also use expressions and variables as arguments to functions. In addition, their results can be stored in variables. For example, we could write:

>>> x = 10
>>> y = 17
>>> max(x, y)
17
>>> z = max(x, y)
>>> z + 4
21

A few more examples:

>>> min(max(1, 2), 3)
2
>>> x = 10
>>> y = -17
>>> max(abs(x), abs(y))
17

## Which of the programs below end in valid functuion calls? Try them out if you're not sure! - [ ] ```max(abs(1) 2)``` - [x] ```min(max(1,2), 300)``` - [x] ```x=100```<br>```abs(max(x,10))``` - [x] ```max(max(4,5),6)``` - [ ] ```abs(abs(max(4,5))``` - [x] ```x = abs(-3)```<br>```max(x,x+1)```
