A Twitter user with the nickname @Wparks91 asked a question on mathematics of primary school and got one answer, but different solutions. In the comments users were surprised that not all are equally suited to the same task.
The question was how people put numbers. “What’s going on in your head at the decision of 27 plus 48” — asked microblogger. Most people started to answer that first stack of 20 and 40, and then the remnants of 7 and 8. They summarize the numbers and find the answer.
