# I Will Predict Your Number – Math Magic Trick

Hi this is Presh Talwalkar

How predictable are you?

Lets find out in this video.

In front of you are the numbers 1 through 16

To get started, I want you to pick a number

You can pick any of these sixteen numbers

But you should remember which number you’ve picked

It might help if you circled it

as you’ll need to remember this number for the rest of the video.

Now I want you to pick a second number.

And I want one condition: I want that number to be in a different row

and a different column from the first number you’ve picked.

So if you picked the number 10 as your first number,

the next number you pick should not be in the same row,

and it should not be in the same column.

So you can pick from any of the remaining numbers

that are not in the same row and the same column as the first number you’ve picked

I also want you to remember this number

so remember the first number you’ve picked

and the second number you’ve picked

You’re gonna repeat this process: pick a third number

that’s in a different row and a different column

from the first two numbers you’ve picked.

So you don’t want this number to be in the same row

or the same column as either of the first two numbers you’ve picked.

So now you’ve picked THREE different numbers

and I want you to remember them

because you’re gonna have to do one more thing

I want you to pick a fourth number

that’s also in a different row and in a different column.

from the previous three number you’ve picked.

So if you’ve followed along correctly,

you’ve now picked FOUR numbers,

and you played according to the rules where they are in different

rows or in different columns

so your numbers might end up looking something like this.

So you’ve got your four numbers

and I want you to ADD up these four numbers

so there’s no way I could’ve known what first number

you’ve picked, or the second number was, or third or the fourth.

But now here comes a prediction.

Add up those four numbers you have

and here is what my prediction is:

My prediction is the sum of your numbers is 34.

Am I correct?

If you want to know how this trick works,

you can follow a link in the video description

where I describe the mathematical proof

in a blog post.

All 4 numbers equal 34

your wrong!!

Very bad man, sorry

His example was my numbers 8,13,2,11

He basically cheated

Simple trick. Since you have to pick a number from different columns and rows, the only posible way is diagonal. and they both add up to 34

10 4 15 1, add 30

What

Me: "10"

doesn't careHim:

says 10Spongebob i'ma head outI picked 2,8,11,13

Um I picked 11 6 3 and 16 and got 36

Mine was 30

Wow

Jokes on him I got 25

No my is 40 🙂

My numbers wete 9 6 3 16 but it still was 34

If you fallow the directions, no matter what four numbers you pick, they are still going to equal 34. I chose 4,15,9,6 and they equal 34. And so does 1,6,11,16.

I got 37

So … i have 46 and not 34 as you said so… now what?

11 6 12 13

How the heck did you know omg 😱

Me: he’s isn’t gonna say 34

Him: most of you had 34

Me: grabs knife

I got 33

Proof can be done using determinants.

Him:Your answer Is 34

Me: drops pencil

Me: How

I chose 13,7,12,2=34

Jokes on you I got 33

I got 35 😂 I chose 15, 12, 7, and 1 🤣

hah i got thirty seven even with the help of a calculator loser 12+15=27+9=37 man screw four numbers

The people whom you can't predict their number:

1. Those who didn't pick

2. Those who are bad at math

3. Those who didn't follow the rules

4. Those who are sleeping

He didn’t even guess my number. He just said “oh yeah this adds up to 34”

Not even close!! You failed

Mine equaled 38 I chose 11,8,5 and 14

These people are scammers the number I picked was not 34 it was 1 they suck at guessing my number

My numbers is 5, 3 14 and 11 so where is the 34??😂😂

I got 13 11 6 4

HOW YOU KNOW!?

This is not predict

Good try you got it wrong I got 36

7 13 12 4

I KNOW HOW HE DID IT…

IF U CHOOSE 4 NUMBERS, NO MATTER WHAT U CHOOSE, ALL POSSIBLE CHOICES ADD TO 34, THIS IS JUST A MIND TRICK MORE THEN ANYTHING!!!

My total is 36

i chose 6, 11, 16, and 14 lol

add em up and i dont get 34 haha

Wow

No! Hahaha

12+1+7+15 hahaha

My number was 7359 this video sucks

Jokes on him because I got 35 …..awkward

I picked 14, 12,7,2 tell me if I'm wrong but that's 35…

35|ALALALA

Maths and common sense…. not magic

I got 30

14+ 8+ 9+ 1 ans 32you wrong

It’s simple 😒

No may answer is 42

Every way possible all equal 34

Every each column you pic the answer is 34

No

Lol I got 56 lol!

If you pick 10,7,16,1 it will be 35

I pick 8, 2, 11, and 13😱😱🙋

Na it has a trick. All number you picked is 34 in total. So of course that asnwer will be 34. Damn predictions.
