[spoiler]it is clear that 1 is the first digit of amount
0 can appear either by the second digit of the first term or the second digit of amount
the sum of the digits in the two right columns should be less than 10, so as not to affect / evenness or oddness of the following columns
and the left column must be greater than or equal to 10
then 623+475=1098, 423+675=1098, 625+473=1098 [spoiler]

belyak62 you did not realize that the example should be all the numbers from 0 to 9.
_gst6907763, all right, but in the job there is one condition about the sum of the digits of the upper number, and then there is one option.
