Bro’s IQ needs to be studied 😳🫡

He made it a multiple of 10 and subtracted 3, answer will always end in 7

Y'all stop shouting is iq is on another level as if he did some high tech shii Any number multiplied by 10 and minus 3 will always give a x7 or xx7 E.g 5 X10= 50-3=47 27 X 10=270-3 =267 99X 10=990-3 =987 So no matter any number you think of,long as it's multiplied by 5 and 2(10) and minus 3,it will always have a 7 at the end

Bro’s operating on a different level . 😭

Swears

He got it 😭😂

😂😂

Nfy 0 0x5 =0 0x2 = 0 0-3= -3. Fake mind readers got nothing on me 😤

Nothing special. If you multiply anything by 5 it will give you something that ends in 5 or 0. If after you do x5 it ended in 5 after multiplying it by 2 it will end in 0. Anything that ends in 0 subtract 3 from it, it always has a 7 last digit. I’ve stolen the trick sha

Try to use a negative number. He’ll be wrong. I used a -2, my final answer was -23.

-3😂😂 My number is 0

Anything multiplied by 5 will either end in 5 or 0. Multiplying that by 2 will always end in 0. So when you subtract by 3 you end up with 7. The only thing that breaks this would be negative numbers.

Well I multiplied it by 0 👀

Bro just did a roundabout way of getting a multiple of 10 and bring it down to 7 by subtracting 3. Don't need a high IQ for that because you can really fk him up by using a decimaled number like 47.2.

Not really. I picked 0 as my number

I picked 0 and my final answer is -3 😂

Not really he just got you to multiply by 10 which guarantees whatever number you thought of ends in a 0 then minus 3 and that last number is 7

Its not that hard to understand: if you multiply any number by 5 i’ll finish by 5 or 0 and if you multiply it again it will automaticslly finish by 0 so when you subtract 3 its always gonna be 7

I thought of 15,230,112 and couldn't multiply that by five so i quit watching.

@thisismide__ How is this smartness? Most of you didn’t finish high school? Subtracting 3 from a number ending in 0 always gives a number ending in 7: 10 − 3 = 7 20 − 3 = 17 30 − 3 = 27 100 − 3 = 97 EGs: 8×2×5−3=80−3=77 23×2×5−3=230−3=227 145×2×5−3=1450−3=1447

I'd have followed if he guessed the whole number.

It’s not some IQ shit btw, it’s a simple maths made to sound tricky.

i mean....its not even that smart. multiple something by 10 then remove 3 it will always be 7. dude just did a bunch of bullshit to try and 'wow' the actually stupid people lol

y’all missing the part where he has you multiply by “2” & “5” which is “x10” lol. therefore, wtv number you choose was going to end in “7” after subtracting “3” regardless.

Yooo this is genius ok, but I got the trick as soon as I heard that 7 any number except 0 multiplied by 5 and doubled is goin to equal to a digit with a 0 at the end and subtracting 3 from it will carry it to wahatever is the other numbers along with the last digit 7.

Nothing special. It works with ANY number. Here's why: Any number multiplied by 5 will end with either 5 or 0 Any number ending in 5 or 0, multiplied by 2 will ALWAYS end in 0. Any number ending in 0, minus 3, always ends with 7 Not rocket science.

27

@swhat03 He’s only smart for dumb people remove 3 from any round figure such as 10 20 30 40 50 and so on and the back number will always be 7 or even single 7 if it 10 I rather called this cunning act not smart so dumb self he try sha

Anything times ten (times 5 and times 2) minus 3 will end with a seven. It's not that deep.

When you multiple a number by 2 and 5 then remove 3 the last digit will surely be 7

Basic trick if you ask me. It may seem high iq to people with low iq. Any number times 5 and times 2 minus 3, the last number will always be 7. 17 x 5 = 85 85 x 2 = 170 170 - 3 = 167. Try this with any number.

Easy trick, whatever number you chose, you’ve multiplied by 10, and anything subtracted by 10-3 would give 7.

The number will always be 7 because he is guaranteeing that the number after multiplied by 5 and times itself ends up ending in 0, so whatever tenth you get -3 will be 7

This isnt some genius thing, he made you multiply by 10, the last digit is always gonna be 7. Its basic math. The second he said the multiply by 5 thing i knew it was gonna be one of these braindead things

retards in comment just discovered that if you multiply something by 10 you'll have a number finishing by 0...

The number I chose was π. You lost me at 'the last digit of your new number'...sorry.
