Context?

The expression could mean anything.

But if I heard someone say they could do 3 digit arithmetic, I would assume they could add subtract and multiply 3-digit numbers (100-999).

it said using 3 digit arithmetic:

*subs in some numbers, 0.2, 100.9 etc into the quad equation and at the end rounds the entire number to 3 digits*

am i right in assuming that all the numbers used to input had to be 3 decimals and then the final number had to be 3 digits?

or does every number in the process have to be rounded to 3 decimals as the number is created? step by step?

What? OfI don't see any difference between using three digits from the outset and rounding to three digits.

Using the numbers you gave as examples, 0.2 would be 2.00 x 10

If you want a better answer, you'll need to ask a question that is clearer.
