This trick uses simple math to read your mark's mind. This is a great trick for kids, since doing it a few times for an adult would likely give it away.

You will need:

- A brain

- the ability to do simple addition and subtraction

<p>haha you got it wrong if the subject choses 12 than the final answer is 6 booom</p>

It's 5<br>12×2=24+10=34÷2=17-12=5

12+12=24.<br> 24+10=34.<br> 34÷2=17. <br>17-12=5.<br>Booom

Hey guys! So I've known this trick for a while, and I've always known that the answer is always half the number you added, but why is this?

<p>hey guys, I choose 6, nvr got it right with 5.pls</p>

Are there any other tricks

<p>dont worry my calculations were wrong</p>

<p>great</p>

<p>Holy Crap! I tired this 3 times and it all equals 5 o.o I know the trick though :P Finally</p>

<p>didnt work for me and i chose 9</p>

<p>i don't think u know how to do maths </p><p>9</p><p>9+9=18+10=28(divided by)2=14-9=5!!!!!!!!!!!!!!!!!!!!!!</p>

<p>noob question;;;;</p><p>let I chose a number as x;</p><p>2(x) == multiply my 2 </p><p>2x+10 == add 10</p><p>(2x+10)/5 = x+5 == divide by 5</p><p>x+5-x == subtract a number I chose at first i.e x</p><p>5 == remaining is 5 ; <a href="mailto:f@ck1ng" rel="nofollow">f@ck1ng</a> question</p>

<p>FINALLY, SUBTRACT THE TOTAL FROM THE FIRST NUMBER YOU PICKED.</p><p>what this actually means is (FIRST NUMBER)-(TOTAL).</p><p>what your supposed to do is (TOTAL)-(FIRST NUMBER).</p>

What is the trick?????

Oh man, I left my brain at home :(

I already known it !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

lol u will need brain hahahaha !!!!!!!!!! nice one

you are right bro

ha ha ha i already knew this trick give me something different

This is a fun trick with a fun purpose

I do this trick with my 8th graders. It works a little better if you say to add 14, so that the final answer is 7. They don't seem to make the connection, whereas they do make the connection with 10 and 5. They won't know exactly how you did it but they seem to figure it out with 10 and 5.

Technically it should be "Subtract the First number from your Total"
If you Subtract the Total from the First number you will get a -5 (negative five).

Nice instructable, it worked perfectly when I tried it!
