Here are some fun, tricky and hard to solve maths problems that will challenge your thinking ability.
1. If 1=3
2=3
3=5
4=4
5=4

2. What is the number of the parking space covered by the car?

Believe it or not, this “math” question actually requires no math whatsoever. If you flip the image upside down, you’ll see that what you’re dealing with is a simple number sequence.

5. There are 49 dogs signed up for a dog show. There are 36 more small dogs than the large dogs. How many small dogs have signed up to compete?
This question comes directly from a second grader's math homework.
Answer:
42.5
In order to figure out how many small dogs are competing, you have to subtract 36 from 49 and then divide that answer, 13 by 2, to get 6.5 dogs, or the number of big dogs competing. But you’re not done yet! You then have to add 6.5 to 36 to get the number of small dogs competing, which is 42.5. Of course, it’s not actually possible for half a dog to compete in a dog show, but for the sake of this math problem let’s assume that it is.
6. Add 8.563 and 4.8292.
Answer:
13.3922
Adding two decimals together is easier than it looks. Don’t let the fact that 8.563 has fewer numbers than 4.8292 trip you up. All you have to do is add a 0 to the end of 8.563 and then add like you normally would.
7. I am an odd number. Take away one letter and I become even. What number am I?
Answer: Seven (take away the ‘s’ and it becomes ‘even’).
Seven
