- Is there an easier way to write written form? it is a bit tiring when you write it.(22 votes)
- Unfortunately not. Written form is the more "expanded" version of standard form, so I suppose instead of writing out "nine hundred sixty-seven" you could just simplify it to 967.

Generally, written form is the kind of thing you learn once and then never use again. It's just useful for learning to speak numbers.(24 votes)

50 thousands is like 5 ten-thousands and 0 thousands.

six hundred thirty-one is just 631.

Add them together: 50,631(6 votes)
