### Can you subtract a 3 digit number from a 4 digit number and get a 4 digit number as the answer?

Absolutely ! There are many solutions - the lowest is... 1999-999=1000 *Side note* Actually, the solution when looking for the lowest value of the term that still gives you a four-digit differance, has to be found in the answer of 1100 - 100 = 1000, since 100 is the - using your word- "lowest" value of a three digit-number, as well as 1000 being the "lowest" four-digit number.
