1. Pick a number, add 2, multiply by 3, subtract 6, divide by 3. You get the number you started with.
2. Pick a number, square it, add ten times the original number, add 25, take the square root (rounding to the nearest whole number), subtract your original number.

Ya its really nice
Hey
The first one is not a magic
It is using Law of Association
Take any number. Say X
Add 2 to it, v get X + 2. Multiply by 3. v get (X+2)*3. the result is 3X+6. now subtract 6. v get 3X. then divide by 3. v get X.
u can try the same with
Pick a number, add 2, multiply by 4, subtract 8, divide by 4. You get the number you started with
About the second trick.
It is not magic, it is algebra.
assume the number to be x. square it, add ten times of the original number and 25 to it. You will get. X^2+10X+25. Now by factorization (spilting the middle term), v can get (X+5)(X+5). now square rooting it. v get (X+5). now. subtract X from it. v get 5.
Thats y wat ever number v take, v will end up with 5.
try this, Pick a number, square it, add twelve times the original number, add 36, take the square root (rounding to the nearest whole number), subtract your original number. you will end up with 6.
Next time when posting some tricks please dont mention the word "magic",
