One of the best ways to stimulate your brain is to solve some fun math problems. However, some people swear they don't like maths, but that won't be a problem today.
These challenges will be fun and exciting, and you will be surprised at how well-prepared you are to solve them.
So, take a shot at this mathematical puzzle and surprise yourself.
Can You Solve This Math Problem?

Think you have the answer already? If you already have the answer, you might want to take another look at the puzzle: there's a hidden trick.
Anyway, if you think the answer is 40, you are so close!
That means you have added 21, which is the solution to the previous equation.
1 + 4 = 5
2 + 5 = 12 (after adding the 5, the sum of the previous equation to 7, the sum of 2 and 5)
3 + 9 = 21 (after adding 12 to the sum of 3 and 9)
8 + 11 = 40 (after adding 21 to the sum of 8 and 11)
Unfortunately, 40 is not the correct answer. There is one little trick you have missed, and it involves the use of a multiplication sign.
The Correct Answer
In addition to using the addition sign, you should also use the multiplication sign. Here is the process:
1 x 4 + 1 = 5
2 x 5 + 2 = 12
3 x 6 + 3 = 21
8 x 11 + 8 = 96
There you go, the right answer is 96, not 40. As you can see, you should multiply the numbers and then add the first number in the equation to the answer.
To solve this problem, you need some critical thinking skills.
Now that you have discovered the trick to solving this math problem, are you ready for a few more?
Other Math Problems
If you are up to it, here is another math problem. It's a little more challenging, and it's a great way to challenge yourself.

As with the previous math problem, you will need to think outside the box in this case as well. You need to look at the numbers very closely.
Can you find the connection among the equations? The truth is that there is a very simple secret to getting the right answer.
You have to look at the connection between several numbers to find the correct answer.
Here is an example using the first equation (8 + 2 = 16106):
8 + 2 = 16106
8 x 2 = 16
8 x 2 = 10
8 – 2 = 6
Each of the problems in the set can be solved similarly. You simply have to multiply the numbers, add them, and then subtract them to get a string of numbers that make up the answer.
How About This Viral Japanese Math Problem
Maybe the last two math problems were too easy for you. This puzzle is a little more challenging.
The math problem went viral in Japan and most people never seem sure of the answer. However, all you need are some critical thinking skills.
Can you solve it?

You don't need a calculator. The trick is making sure you solve each part of the equation in this order:
B - Brackets
E - Exponents
D - Division
M - Multiplications
A - Addition
S - Subtraction
The brackets should come first, followed by parts that have exponents, then divisions, before doing multiplication. Finally, you should add the totals and then do the subtraction.
Here is a video to help you understand this process.
How many of these equations have you gotten right? Even though you might have missed a few, hopefully, you had a lot of fun in the process.
