One of the basic principles of good illustration is to label things where appropriate. But this article has two illustrations with the same unlabeled three colors. "Adding π2/6 and e using

Notice that if you try to add up the 9s on the ones place column, you end up with 108. You can simply write the 8 as the ones place in the column, but what about the 10? You're not carrying 1 digit, but 2 digits instead. Do I simply treat the 2 digit as a single number, like 10+(9*12) = 18 with the

Concluding from this that bees can "perform basic maths" seems.... very liberal with definitions. To me personally this seems much closer to "rat memorizing a maze" than to a person or animal learning to add and subtract. I would skip mentioning this study here, but it might belong in some kind of

I have looked at the
Dedekind cuts version of the diagram, and thought about it fot some time, and I absolutely cannot understand it at all, so, adding to that the two comments above from you and someone else, I have removed it. The Cauchy sequence version I can understand, so I've given it the

digit result), you have a couple of options: you can carry the whole overflow into the next column, or carry each digit of the overflow into the respective columns. So in your example, you can write 18 in the tens place and continue adding, or you can write an 8 in the tens place and a 1 in the

This experiment showed that if you do many many training runs with bees where you show 2–3 colored shapes next to an entrance to a Y-shaped room with two further examples of several shapes, one side of which leads to sugar water, where the "correct" choice had 1 shape more than the original

This seems impossible to clarify, as the scale (values corresponding to horizontal lines) as well as the meanings of colors and arrows are not defined. Even with the lacking definitions, I suspect that the figure would remain confusing. So, I have removed the figure.

hundreds place. These methods are ultimately the same – if you put the 10 in the tens place, at the next step you will simply have an overflow of 1 more than you do with the other method, which leads to an extra 1 in the hundreds place.

benefit of the doubt and left it in place. However, I doubt that it would actually help anyone to understand the concept if they didn't already understand it, and I wouldn't quarrel with anyone who decided to remove that one too.

While adding 2 numbers at the highest digit will never be able to reach the 3-digit threshold (9+9=18), but what if you are adding far more than 2 numbers? For example 999*12 but you do this with only addition?:

One of the images (2+4=6) uses the word 'translation' to explain it; how-ever, "translation" is not used any-where else in the article. What does it mean?
