Introduction

Using maths with variables


It’s all very well doing maths, but if you are just typing in calculations, you might as well just be using a calculator! Maths really only starts to get useful in Python when we start storing the results of calculations. Once we have stored the result as a variable, we can either do more calculations we the result, print the number to the screen or do something else with the value.

Demo
y=4
z=x+y
print(z)
9
Practice - Part 2

Practice question 4
Use python to solve this maths question:

x = 45
y = 87
z = x + y

What is z?

Practice question 5
Use python to solve this maths question:

l = 10
w=20
a = l * w

  • What is the value of a?
  • What is this the equation for?

Practice question 6
Use python to solve this maths question:

pi = 3.142
r = 20
a = pi* r

  • What is the value of a?
  • What is this the equation for?

Introduction

Using maths with brackets


Just like in standard maths you can use parentheses (aka brackets) in Python. Though I bet in maths class making these kinds of calculations aren’t as easy as just typing in the code?

Demo

Practice Part - 3

Practice question 7

Use python to solve this maths question:

(4 * 4) + 4
Practice question 8
Use python to solve this maths question:

4 * (4 + 4)
Practice question 9
Use python to solve this maths question:

(25 + 45) / ( 5 + 5)
