Why is twice 10 like 2 times 11?

There is two ways that could be possible for this. One is that twice 10 is like the clock, twice then 10 also meaning 10 at night. In 24 hour time, this is 22:00

The other way is the spelling and maths. 2*10=twenty and 2*11=twenty too

Notice that when you say it, it is the same thing as 22. However, the two is spelt as 'too' in this situation
