Fun With Maths Riddle: If 5 – 4 = 23; Then 2 – 4 = ?

Have fun with Maths with this number logic riddle.


Given below are some equations that follow a similar logic, can you find that logic?

Once you find the logic, you can easily find the value of ? in the last equation.

IF;

5 – 4 = 23

8 – 1 = 63

6 – 16 = 32

9 – 9 = 78

Then;

2 – 4 = ?


If you get the answer, challenge your friends on Facebook and WhatsApp and see how many of your friends can solve this faster than you.

Answer:

The logic is :

sq(5) – sqrt(4) = 25 – 2 = 23

sq(8) – sqrt(1) = 64 – 1 = 63

sq(6) – sqrt(16) = 36 – 4 = 32

sq(9) – sqrt(9) = 81 – 3 = 78

Hence we can find the missing number with the same logic.

sq(2) – sqrt(4) = 4 – 2 = 2

Answer = 2
