Mathematics help with this and working too

Never heard of this but I'm guessing

face = 2

I know the the

actual = 2000

Step-by-step explanation:

try these

Face value = 2

Actual value = 2 000 or 2,000

      The face value is the number / what it looks like, but the actual value is what the number represents in the number. This is why that 2 is actually 2,000.

     Hope this helps, have a nice day :D
