adding or joining , as performed
R a+b=c same as now, combined numbers 222+33=2253, when they are the same along (gap) they are joined, here 2 and 3, we get 5
R2 here there is an operation function (the same applies to other Rn) , 1(R2) 3+14=(3,42) , 2(R,R2) 3+24={7 ,(3,42)} , 3(R-R2) 3+34= (7, 42)},4(R,R2,R-R2) , 3+4 4={7,(3,42) , (7.42)}
(2,32)+(3.32)=(5 .62)
R3 5(R,R2 , R3) , 3+54={7 , (3 ,42 ), (3 , 0 , 43)} , 6(R-R2, R3) , 3+64={( 7 , 42) , ( 3 , 0 , 43} , 7(R, R2-R3) , ...so on
