Zero is the number that represents no amount or objects. When we add zero to a number, the result is just the number, unchanged.

To find the total, or sum, by combining two or more parts (addends), or to increase an amount by adding another.

To partition one part from another (the subtrahend from the difference), or to decrease an amount by taking an amount away.

The equal sign is used to show that the values on either side of it are the same.
