Let's now create a 32bits adder.
This operation could be done directly by adding a simple constraint `out === in1 + in2`,
but doing this the operation would not be module `2**32` but `r`, where `r`is the range of the elliptic curve. In the case of regular (regular??) zkSNARKs this number is typically some prime close to 2**253.

So, the strategy we will follow will be to first convert a number to binary, then do the addition using the binary representation (regular electronic circuit) (<- què vols dir amb això de regular electronic circuit??) and finally change it back to a number. (?? You mean base10?)
So, the strategy we will follow will be to first convert a number to binary, then do the addition using the binary representation like in regular electronic circuits, and finally change it back to a number.
To do this, we create 3 files: `bitify.circom`, `binsum.circom` and `sum_test.circom`.
