Incredible how easily our brain is fooled: what is 1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10? Watch out for the trap.
Our brain is deceived every day because it is subjected to hundreds of stimuli at the same time: being multitasking, in fact, is not an advantage ( here the details ), however even when we watch too much television or often use the navigator , we put our brain cells on standby. causing them to rust. Worse still if it is optical illusions ( can you see the chick among the bunnies? ) Or math puzzles: it happens to go haywire and not see beyond our nose, lose all logic and fall into the trap.
We recently challenged you with a series of operations that are only apparently easy , but which instead turned out to be more difficult than expected as 8 + 8 x 0 + 5 x 0 + 1 ( here the solution ) and now we propose another calculation mathematical that you will have to carry out rigorously without a calculator and quickly : if you give one answer rather than another it means that there is a small and very common bug in your brain .
So are you ready? I recommend you do the calculations in mind, even pen and paper are banned!
You have 1000, add 40.
Add 1000 more.
Add 30 and 1000 again.
Add 20.
Add 1000 again and then 10.
Did you answer 5000 too? Well, we are sorry to inform you that you messed up!
The correct result is 4100 , and if you don’t believe it, grab the calculator and do the math again. You will realize that you have confused the hundreds with the tens because the decimal sequence confuses our brain which naturally tends to jump to the highest decimal, therefore to the hundreds instead of the tens.
You may be comforted by the idea that the mistake is quite frequent, but to overcome this lack of mental training and stimulate you, we suggest you stock up on these magical foods , which help our brain to stay in shape, or at the most to make you give chicks repetitions because it has been shown that they know how to calculate and know the basics of math!
