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)
