Displaying it as we often do with an addition problem. Find the values of the questions marks if this addition is true in base 5.
I can help you with the units digit. Since two plus three is five and five in base five is 10_{5}, the units digit of the difference between 3000_{5} and 2342_{5} is 3 and hence
If you learned the addition algorithm the way I did then you carry a 1 into the fives column. What is the value of the question mark in the fives column? What is the value of the question mark in the five squared column? What is the value of the question mark in the five cubed column? You can use addition base five to check if your answer is correct.
