there is no solution in the current mathematics :

1.3+[0]3=3

2.3+[1]3=4

3.3+[2]3=5

4. 3+[3]3=6 or 3+3=6

5.3_{3Rd1(6)d2(7)}+3=7

6.3_{3Rd1(6)d2(8 )}+3=8

7.3_{3Rd1(6)d2(9)}+3=9

8.3_{3Rd1(6)d2(10)}+3=10

9.3_{3Rd1(6)d2(12)}+3=12

(1,2,3,4) - there are several types of addition in the set N

(5,6,7,8,9) - that there are dynamic numbers, where this can add
