\starttyping ∀(i, k) ∈ I×K: C(i, k) ≔ ∑_(j∈J) A(i, j)·B(j, k) \stoptyping You need a font which has the necessary symbols or you take the missing one from another font but in this case you should look for one which has a similar style as the main font (which is not the case in my example).

Your example is missing the \starttext and \stoptext. Wolfgang
