```julia
## integer comparisons ##

(<)(x::T, y::T) where {T<:BitSigned} = slt_int(x, y)

(-)(x::BitInteger) = neg_int(x)
(-)(x::T, y::T) where {T<:BitInteger} = sub_int(x, y)
(+)(x::T, y::T) where {T<:BitInteger} = add_int(x, y)
(*)(x::T, y::T) where {T<:BitInteger} = mul_int(x, y)

```

It seems to me that add\_int is a function however I don’t know where to find how it is implemented

it’s an intrinsic defined in C. You can see the list of them [here](https://github.com/JuliaLang/julia/blob/master/base/compiler/tfuncs.jl), and the implementations [here](https://github.com/JuliaLang/julia/blob/master/src/intrinsics.cpp) and [here](https://github.com/JuliaLang/julia/blob/master/src/runtime_intrinsics.c).
