Python can function as a basic calculator, allowing you to perform computations, however basic, much faster than most of us could using our own brainpower.

Here is a basic example:

print(1 + 1)

This will output:


Notice how we use print statements from Lesson 1 to display the output of this addition. Now this was a pretty simple calculation, but how about this one:

print(1581 * (7502 / (3.5 + 1)) - 0.25**5)

In less than half a second, Python outputs:


Notice here that we utilized addition, subtraction, multiplication, and division in this one expression, with some not so friendly numbers! We also added an exponential (denoted by the double asterisks **) at the end.

Let’s now practice doing some other computations in Python:

  1. Compute the sum of 3 and 5. Divide it by the product of 10.5 and 0.6. (solution)

  2. Compute the product of 12345 and 6789. Then subtract from it 0.951. (solution)
