The digits that fill this addition are 5 (digit A), 7 (digit B), and 0 (digit C).

How to complete the digits?

The image shows a simple addition of three numbers, knowing this is an addition we can use smaller additions and substractions to correctly complete the digits missing. The process is shown as follows:

  • Digit A= 6+A+2 = 3 (this represents 13). Based on this: 13 = 6+A+2, therefore: A= 13- 6+2= 13 -8 = 5.
  • Digit B = 3 + 9 +4 + 1 (from the previous column) = 7.
  • Digit C= 5 = 3 + 1 + 1 + C (from the previous column). Therefore, C = 5 -5 = 0
