Example: How many stones?
There are 4 stones in a pack. The path needs 32 stones.
The calculation can be written like this:
y 脳 4 = 32
Division is the opposite of multiplication. Move all the numbers to the opposite (right) side of the equation so you can do division.
y = 32 梅 4
32 梅 4 = 8
y = 8
To make the path you need 8 packs of 4 stones.
