A brain teaser stunned internet users as many got the same answer after following simple maths steps.

Brain teasers have long fascinated people by challenging logic and making them question how their minds work. Social media has only amplified that curiosity, with puzzles and riddles often going viral as users rush to test them on friends and family.

The viral post, shared on Instagram by a user named Scotty, features a sequence of images with handwritten instructions that guide viewers through a seemingly random maths exercise before leading them to a surprising conclusion.

The handwritten text in the post reads: "Think of any number between 1–10. Multiply that number by 2, now add 8, now divide by 2, and now take your original number and subtract it from your current number. Now turn whatever number you have into a letter: 1 is A, 2 is B, 3 is C, 4 is D, 5 is E, and 6 is F. Think of a country that starts with that letter. Now go to the next letter, for example, if you had B go to C, if you had D go to E, or if you had E go to F, and think of any animal, big or small, that starts with that next letter. Finally, think of the colour of that animal. There’s no grey elephants in Denmark."

Why most people got the same answer

The trick works because the maths equation almost always leads participants to the number four. That corresponds to the letter D, prompting many people to think of Denmark as the country. Moving to the next letter, E, often leads people to think of elephant. The final step results in many choosing the colour grey.

Scotty captioned the post: "Someone showed me this trick when I was a kid, I still remember it see if works on you. Check your math and dont make a big deal its a kids trick for fun. Dont read the comments first."

Internet reacts

The post quickly drew reactions from users who were shocked at getting the same answer. "Why did I actually think of Denmark?" wrote one user. Another commented, “Grey elephant was exactly what I got. This is scary.” "I checked the maths twice and still ended up there," said another. One user added, “I thought I was being original but apparently not.” Another wrote, “This messed with my brain for a minute.” "Okay, that was way too accurate," read another comment.
