How to calculate the sum of 2 numbers with BrainFuck

Question

I\'m trying to write a program with BrainFuck that can read two numbers up to 9, calculate the sum of them and then print the result out, e.g. 3 & 5 give the result 8 .

Answer 1

I've created a solution that can add ANY NUMBER OF NUMBERS with ANY NUMBER OF DIGITS:

,[+>,]>++++++++[<<[------<]>[>]>-]<<[++++[----[<]<+[<+<+>>-]<<[>>+<<
-]>[<<<[<<]+[>>]>-]>>>>[>]<-[[<]<<<<<[<<]>>>+>[>>]>>>>[>]<-]<[<]<<<<<[<<]>>[[-]>
>]>>>>[>]>+<]>-[<<[<]<[-]>>[>]>+]<<]<[-]<->>>>>->+[[-]>+>[<]<]<->>+>->+[>>+]<<[+
[--[>+>+<<-]>>[<<+>>-]>+<<[>++++++++++<[->-[>>]<<<]>>>>[<<<----------<<+>>>>]<]>
>[-]<<<[[-]<[-]<<[->>>>>+<<<<<]]<]<]>>>>>>>>>>[<<]>>[+[->++++++++[<++++++>-]<.[-
]]>>]

For example:

input:  13611+85399+35943
output: 134953

Make sure "Memory overflow behavior" is set to wrap.
