Now that we know how to create variables and update their values, we can start using them in calculations. Programs use maths constantly — especially in games. Damage, armour, speed, experience points, currency — all of these rely on mathematical operations.

Python uses simple symbols for common operations:

total = a + b      # addition
remaining = a - b  # subtraction
result = a * b     # multiplication
split = a / b      # division

These operators work with variables just like they do with numbers.

Assignment:

In World of Software Engineering, our hero equips powerful armour. The armour doubles their effective health. Create a new variable called: armored_health Set it equal to: player_health * armor_multiplier Then print the result.

player_health = 1000
armor_multiplier = 2

# create armored_health here

print(armored_health)
