#Minecraft 1.10, 221 characters (non-competing)

See, this is what we have to deal with when we make Minecraft maps.

Aside: There's no way to take a string input in Minecraft, so I'm cheating a bit by making you input the numbers into the program itself. (It's somewhat justifiable because quite a few maps, like Lorgon111's Minecraft Bingo, require you to copy and paste commands into chat in order to input a number.)

Thank you abrightmoore for the Block Labels MCEdit filter.

scoreboard objectives add a dummy scoreboard players set m a 6 scoreboard players set n a 8 scoreboard players operation r a += m a scoreboard players operation r a += n a tellraw @a {"score":{"name":"r","objective":"a"}} 

Non-competing due to difficulties in input, and I have no idea how to count bytes in this thing (the blytes system is flawed for command blocks).
