Capacity is the amount of liquid a container can hold.

 

L = litre

ml = millilitre

 

Examples:

Add 5 Litres and 1 Litre.

5 L + 1 L = 6 L

Example 2

40 ml + 30 ml = 70 ml

 

Examples: 3

Subtract 15 Litre from 20 Litre

 

20 L – 15 L = 5 L

Bigger number at the top while smaller number at the bottom.
