Numbers in Python can be positive or negative. If a number is positive, it increases something. If a number is negative, it decreases something. To make a number negative, simply place a minus sign in front of it. Example:

damage = -10

This tells the program to subtract 10 instead of add 10.

In World of Software Engineering, our hero has stepped into hot lava. Instead of losing health, the hero is accidentally gaining health. We need to fix that.

Assignment:

Change the value of lava_damage so that it reduces health instead of increasing it. Do not modify any other lines of code.

player_health = 100
lava_damage = 10

# don't edit the code below

player_lava_health = player_health + lava_damage

print(player_lava_health)
