Ahha, recently my daugher come to me with 3rd grade math problem. "Without rearranging the digits 1 2 3 4 5, insert mathematical operation signs and, if necessary, parentheses between them so that the resulting expression equals 40 and 80. The key is that you can combine digits (like 12+3/45) but you cannot change their order from the original sequence 1,2,3,4,5"

Grok3, Claude, Deepseek, Qwen all failed to solve this problem. Resulting in some very very wrong solutions. While Grok3 were admit it fail and don't provide answers all other AI's are provided just plain wrong answers, like `12 * 5 = 80`

ChatGPT were able to solve for 40, but not able to 80. YandexGPT solved those correctly (maybe it were trained on same Math books)

Just checked Grok3 few more times. It were able to solve correctly for 80.

Looks correct to me on 3.7 extended (albeit with loooots of thinking) although I'm incredibly exhausted so I might not be mathing correctly:

It found two solutions for 40 but one of them omitted the 5 the other added a 3.

12 * 3 + 4 = 40

1 * 2 * 3 * 4 * 5 / 3 = 40
