People on the internet were in disbelief that a fifth-grader was expected to solve the problem.

Math isn't everyone's favorite subject, especially when it comes to solving complex problems during exams. For many, the dislike of math persists into adulthood. A Reddit user, u/springwaterh20, shared a math problem from their brother's exam, sparking a wave of hilarious comments. While some found a straightforward solution, most reacted with humorous frustration. Adults struggled with the problem, and were stunned to learn it was intended for fifth-graders.

"A test problem on my 5th-grade brother's math exam," the user captioned the post. Below is an image of the question that reads, "Klein read 30 pages of a book on Monday and 1/8 of the book on Tuesday. He completed the remaining 1/4 of the book on Wednesday. How many pages are there in the book?" Turns out, the kids were allowed to take their tests home for correction and the fifth-grader's father couldn't solve this problem. "My dad sent this to me because he couldn’t figure it out. I had to sit down and write this one out," the user mentioned in a comment. The kids were supposed to identify the number of pages in Klein's book and people could not help but take a jive at this unknown Klein in amusing ways.

"The whole thing stems from an assumption that Klein started the book on Monday. This is not explicitly stated. He could've been reading that book for a week before Monday - we only have Monday’s page count. Now how do you people who were able to answer a fifth-grade fraction problem feel?" said u/VinterKnightSr. To this, the original poster replied, "You are correct. The 5th-grade students were actually supposed to model the number of pages using a probability density function. No one got it right." u/DirectionNew5328 jokingly said, "Why didn’t Klein just read the remaining 18 pages on Monday? Klein is lazy," to which the user quipped, "He’s got a lot of bottled-up stuff going on, okay?"

Many, including the user who posted the problem, eventually solved it. Since Klein read 3/8 of the book on Tuesday and Wednesday, he must've read 5/8 of the book on Monday, which was 30 pages. So, if 5/8 of the book was 30 pages, the total number of pages in the book was 48. "The problem is though, of course, I used algebra to set up and solve this, and I assume this would have been cheating since 5th graders probably don’t know how to solve for things algebraically yet," the individual said. They felt that it was too advanced for a fifth-grader and many could relate to this opinion.

How would you fare in this Harvard math entrance exam? The exam was given in 1869, so no calculators allowed! pic.twitter.com/fCycZk1QrC

On a similar note, a Harvard math entrance exam from 1869 when calculators weren't allowed baffled the internet. Anthony Bonato—who goes by @Anthony_Bonato on X—a Canadian professor shared a picture of the Harvard math entrance exam that was over 150 years old. Considering the fact that no calculators were allowed during exams back then, people were stunned at the long-form arithmetic, logarithm and trigonometry questions.
