Everyone hates math (REDDIT)
A young man was left stunned after seeing a question on his little brother's 5th grade calculus test.
The purpose of the question shared on Reddit was to try and figure out how many pages there are in one book.
"Klein read 30 pages of a book on Monday, and 1/8 of the book on Tuesday," the question reads, "He completed the remaining quarter of the book on Wednesday. How many pages are there in the book?".
Most surfers on the social network were shocked after the question was posted.
"Now we can all ask the obvious question - "Are you smarter than a child in the 5th grade?", with this question as a questionnaire" voiced one of the respondents and another added: "I found out today that I would have failed math in the 5th grade."

As mentioned, most of the respondents did not like the style of the question and claimed that it was too difficult or illogical, "I always said to myself: "People need to be tested on basic skills before they can be allowed to be part of society", wrote one of the respondents, "Now I understand that I shouldn't be Part of society."
Not everyone agreed that the question was too difficult, "I don't want to be rude, but what is interesting or special about this question?" wrote one, "It looks like another math question I would have solved in the fifth grade." More questions that confused

Then a man with a professor's degree in engineering, with a background in applied mathematics, came to everyone's aid, who said that the question was not difficult, but that one should add to it the assumption that Klein started reading the book on Monday.
Once you've done that, you can easily solve the question - because it's five eighths of the book, divide by five and multiply by 8 and find out that the book has... 48 pages.

More commenters responded with their solution and many had their own way of solving the question, but the answer was always the same.
Some used ChatGPT for help, others a calculator and some of them actually calculated by themselves in their head: "It's 48. The equation is
30+0.125X+0.25X = X
- then you find what the x is. It's algebra but I don't remember if it's What I learned in the 5th grade. I'm a child of the 80s and we didn't have Siri or Alexa to give us the answer :)."
Meanwhile, some surfers were not at all concerned about math matters and wondered: "Why didn't Klein just read the remaining 18 pages on Monday? Klein is lazy."
