One equation ~1+1=?~

One and zero is one
One times one is one and that's all
One and one will be two
One times two will be two of us
We'll be together as one
One of us will become all together
All we want to live without isolation,
isolation, isolation.
All we have to be within cooperation
Formuration, communication.
1とゼロを足すと1で
1かける1も1で
1と1を足せば2人で
1かける2でも2人だよ
2人は1つなんだけどね
