# Numbers

The computer can also do math. Use print() to print out the result from the math expressions. No quotation marks are needed for numbers! Unlike strings, you can do math on numbers.

print(7-3)  #prints 4
print(5 * -6 + 7)   #prints -23
print(24 * (8-3) / 6)   #prints 20.0


You can also try using the math symbols to make your own expressions!

### Challenge 1

Let’s try to figure out the answers to the following using Python. Try printing out the result of the below (make sure you don’t miss any parentheses):

• 2 - 19
• (3 + 5) * 6
• (13 + 5 * 8) / (6 - (3 + 7))

### Challenge 2

Can you print out this statement? "527 time 199 is: __"

You will fill in the blank with the answer of what (527 * 199) is. If you want to print a string and a number together, you first have to convert the number into a string.

Here’s an example: print("Hello, World!" + str(5))
