11-Second Math Challenge: Find the Final Equation Value

Brainteasers are known as entertainment sources but apart from being a leisure activity, they also serve many benefits. For example, math puzzles help in improving cognitive skills which further enhances the areas of the brain linked to reasoning, memory, and pattern recognition. When you sit down to solve a mathematical brain teaser, especially under a time limit, your brain gives preference to structured thinking. 

A research study from Eurasia Journal of Mathematics, Science and Technology Education mentions that the puzzles, “serve as a powerful tool for the development of mathematical skills: ability to think logically, ability to abstract thinking, combinatorial abilities, aptitude for spatial representation and manipulation with spatial images, critical thinking abilities, mathematical memory as a specific ability of mathematical activity"

That is why math based brain teasers can prove quite effective as they require both logic and creativity. 

Now you need to take a look at today’s viral math brain teaser which presents a sequence of number equations that appear unusual. Each of these lines follows a pattern and your task is to discover that pattern and apply it to the final equation.

There’s one twist: You only have 11 seconds.

This time limit is not to induce stress but to improve your attention span. When your brain is guided to work within a short time window, it filters distractions and prioritises pattern recognition. 

Start the timer. All the best!

Did you notice how the first pair of numbers changes into a two-digit result? This shows that the answer is not random as it is built from the interaction between the two numbers.

Here are some tips that can help you solve this puzzle easily: 

• Break each equation into parts

• Compare across rows

• Look for combined operations

Did you find out a pattern? If not then you need to hurry up as there are only 5 seconds left on the clock. 

Puzzles like this are created in such a way that they make you think outside the box. 

And 3… 2… 1! The time limit finishes

Did you recognise the pattern?

If yes, that’s a strong indicator of analytical focus. If not, it is alright. Brain teasers are designed to interrupt automatic thinking and reward careful observation.

Find the Value: Solution

Each equation follows this rule:

First number − Second number

followed by

First number + Second number

If we observe the pattern it can be easily solved. 

Equation 1: 5+3 =28 which means 

5-3=2

5+3=8

So the answer is 28 

The pattern continues where the second equation shows: 

9+1=810

9-1=8

9+1=10

So the answer is 810

Similarly if we follow the pattern, then the solution for the last equation would be: 

7+3=?

7-3=4

7+3=10

So deriving the answer from these equations would be 410.

This type of math brain teaser rewards pattern recognition more than traditional arithmetic. Hope you enjoyed this puzzle. Share it with your friends and loved ones and see if they can recognise the pattern and solve it within a time limit or not.
