What does it mean to "write the sum"? The exercise

what level ?
middle school for the retarded ? learn to use Sigma and write the sum without computing the closed form
college ? compute it, even if it's not asked it shouldn't be too hard I guess

I tutor children at all levels from all over the world; this particular example was for K-1 students.

I find it to be a poorly formed instruction that is probably a simple mistake on their part, but I wanted to find out if this wasn't some kind of regional misunderstanding.

If it is just a quirk of the language found in a specific region, I'd like to know that and be able to research it so that I can explain it rationally to people.

I'm not an expert of dialects or anything, but for my money it sounds like the authors of the exercise were just fucked. What information was given with "each"?

Doesn't matter. I've never heard of any English speaking population where "write each sum, then answer the question" makes sense.

It might just mean "copy them down onto your worksheet / workbook".

Good point. Unfortunately the exercise appeared in a printed workbook where you were supposed to put all work and answers so that does not answer our particular question. Thanks for your response.

An Infinite supply of chocolate!

Though it sucks how the bar is noticeably shorter on the loop, kek. if the maker had really wanted to keep the illusion then he would have paid attention to that detail.

I think he tried, that's why there's a visible gap left in the diagonal cut.
