Try it

Numbers without a symbol are implied to be your base currency:
Numbers with a symbol — include the currency symbol ($, €) before
the number ($20.50, €10), spaces allowed:
Numbers with a currency code — a 3-letter code (EUR, USD, EGP)
before or after the number. fx even tolerates typos and stray
spacing, so USD100, $ 100, 100usd, 100 uSd, and usD100 are all
the same:
Grouping
Use parentheses () to group terms and control evaluation order, same
as any calculator.

Or write them out verbally (10 thousand), or with commas
(10,000) — all three represent the same number:
