12+12=9

25+25=49
18+18=81
29+29=???????

um...dude...are u joking right now?

first of all here are the correct answers...

12 + 12 = 24
25 + 25 = 50
18 + 18 = 36
29 + 29 = 58

Are you joking its a riddle and your answer of 58 is so wrong.

121

well, if this is a riddle, come back with a serious question. this is a homework help site, not a "solve my riddle" site.

herp_derp your answer is soooooo wrong. What you gave me was simple math or you joking

ok...either you did not read my comment or you are purposely ignoring it. my answer is "wrong" to you. ok i get that, i honestly don't care since its a riddle. This site is only meant to be for REAL questions/problems, NOT riddles, etc...
