There comes a time when you just can't help your kids with their homework anymore. Too many years have passed, and little tricks like "multiply by -1" and "change the sign" have gone by the wayside.
But surely we can assist until they reach high school, right? Middle school?
OK, fifth grade at the earliest.
This standardized test question for 6- and 7-year-olds, though, has us reconsidering.
The question asks: "There were some people on a train. 19 people get off the train at the first stop. 17 people get on the train. Now there are 63 people on the train. How many people were on the train to begin with?"
The math problem is aimed at second-grade students in the U.K., and its level of difficulty caused quite the stir among parents — many of whom are stumped by the correct answer.
Louise Bloxham first shared a picture of the question on Twitter, almost immediately sparking discussion and debate on the topic of standardizing testing, The Huffington Post first reported.
One user voiced concerns that the problem placed "ridiculous pressure on children who are 6-7 years old."
Others, though, felt that the question was actually age-appropriate and didn't deserve the massive amount of attention or outrage.
"It's really pathetic that this question is getting such publicity," one user fired back.
What do you think? Can you solve the problem?
X - 19 + 17 = 63.
So, X (the original number of people on the train) = 65.
But as one user pointed out ... that's algebra!
