Ok, here it is:
Choose any arbitrary numbers x and y.
Then use the following relation defined by Lemma * from Abstract Mathematics as
x+y=(x+y)*x
given x=2, y=3 then
2+3=(2+3)*2=5*2=10
given x=7, y=2 then
7+2=(7+2)*7=9*7=63
given x=6, y=5 then
6+5=(6+5)*6=11*6=66
given x=8, y=4 then
8+4=(8+4)*8=12*8=96
given x=9, y=7 then
9+7=(9+7)*9=16*9=144.
That's what I had, endelea kutupa test nyingi ili tujipime zaidi.
