about the earbud.
The earlier equations show a pair of earbuds, while the final equation shows only one earbud.
Therefore, we must divide the value of a pair by 2.
One earbud is worth 5.
The person is still worth 5, and the single watch is still worth 2.
But don’t rush to add these numbers together!
There is one final rule to remember.
In mathematics, multiplication must be performed before addition.
This means we must multiply the value of the person by the value of the watch first.
Five
