MAGIC MATHEMATICS


This is what I call magic
mathematics! Bring out your
calculator and do this:
1. Take the last digit of your
phone number.
2. Multiply by 2
3. Add 5
4. Multiply by 50
5. Add 1766
6. Subtract your year of birth
7. You will get three digits
8. The first digit is the last digit
of your phone number
9. The remaining digits are your
actual age...
Any objection?

The first one didn't work

The answer to the last question is 1

Wrong last one is 12. PMDAS multiply 1 x 0 first then add the rest.

Either 30 or 2. At the end of each line there is not a mathematical operation. So one can go two ways with it. First way is that the numbers wrap around thus making 11's ( making 30) OR that the last line is the only one that matters, making it 2.

Yeah it's 12. You have to multiply 1x0, and then add 1+1+1+1+1+1+1+1+1+1+1+1 to get 12.

1+1+1+1+1 1+1+1+1+1 1+1*0+1=2

The awnser is 12+1x

1+1+1+1+11+1+1+1+11+0+1 = 30

12 ones is 12 then it becomes 12 times 0 which is 0 then plus 1 equals 1 that is your answer

I mean, the answer already says it's "?", you don't even need to do any math

It's 300 or 120

No the answer is 13. Any number times 0 is that number. So 1 X 0 is 1. After that just and the others.

If you add first line you get 5. If you add second line you get 5. If you add third line you get 1. (Anything x 0 =0 so 1+1=2×0=0+1). If you add all lines you get 11. But problem does NOT have a line under it or a plus sign to indicate you should add together. So I think the answer is 1. Because that is the line that has ? and needs solving.

The are some really dumb people in this world. The only correct answer is twelve.
Not 2, not 13, not 1, not 300...smh

Add EVERYTHING up until you get eleven then it asks you to add 1x0. That is zero. Then add one. It equals 12.

No one is dumb, you don't actually know how it asks you to solve either from left to right or following the mathematical way. So in the end either 1 or 12 could be right.

There is actually no indicator that the three rows are added together but the first row is 5 the second is 5 so the third is 5 and what may be seen as a multiplication sign is actually the letter variable x so the problem is actually (1+1x)(0+1)=5 or just 1+1x=5 therefore the answer is x=4.

You multiply and divide before you add and subtract. 1X0=0 Therefore: 1+1+1+1+1+1+1+1+1+11+0+1=21. Many are missing the fact that there is an 11 in the equation because it falls into 2 lines. But then again almost everyone here has a different answer and interpretation to the math problem.

No matter how many lines or any other number it's still gonna be 1. However great the number times 0 id's gonna still be zero, then+1=

1x0=0, anythingx0=0. So the correct answer is 1.

The correct answer is 2. Notice that there are no pluses on the end top rows therefore
1+(1x0)+1=1+0+1=2

I got 13 , but maybe I can't count , idk !

The first one didn't work. Not even close, I did the math 4 times by hand and 3 times with a calculator and got the same answer every time.

No did a mistake

There is only one "1" in the third line So again:

1+1+1+1+11+1+1+1+11+1+(1X0)+1=30

In anther way we have four "1"s in the first line adds 4
Three "1"s in the second line adds 3
One "1" in the third line adds 1
Eleven from the first and send lines adds 11
Eleven from the second and third lines adds 11
Zero from the multiplication 1X0 adds 0

Now 4+3+1+11+11+0=30

12X0=0 0+1=1 hence the answer is 1

There should be parenthesis or else this equation is not correct

Most of you are idiots stay in school

Last line says 1+1x 0+1=?. In order to get 2, you have to read it as 1 + (1x × 0) + 1 = ? or 1+0+1=? which leaves us with 2. However, like with the first 2 lines, there are no operators between 1x and 0. If this is true, then the last line is really 0+1=? Which is 1. The first 2 lines and the first part of the third line have no effect on the answer as they are not part of the equasion.

Ok, so let's break this puzzle down for better understanding....First of all there are no mathmatical symbols between lines 1 and 2, as well as no mathmatical symbols between lines 2 and 3. This excludes any answer for adding up the first 2 lines. They have no affect in the actual solution. The 3rd line is actually broken into 2 parts. The first being 1+1x. No symbol between the 1x and the remander of the line. It has no affect on the answer. The only part to solve is 0+1=?. The true and only answer would, and is 1.

People, it's 12! Multiplication comes first! Then you add the others 1's! Simple!

The answer is 30 because there are 5 one's in each row but there is no + in between the first and second row and the second and third row so the equation is actually 1+1+1+1+11+1+1+1+11+(1x0)+1

I think the first three rows are red herrings; solving for last row, the answer is 2

Without parentheses in the calculation you must follow the "order of operations" which states from left to right do the multiplication and division first then do the addition and subtraction. So 1 multiplied by 0 is 0. Now do the addition. The answer is.... 12

Write it out in one long line........do the math.......and you get 30. If you multiply "something" by nothing you get "something". (Because you are not multiplying it) my answer is 30

2 because the first two lines are not part of the equality given on the last line.

As Rambunctious says the first two line at notpart of the equation and are not complete equations, no equals signs. This makes the answer 2

I don't see any answer but 30 (= 1 + 1 + 1 + 1 + 1 1 + 1 + 1 + 1 + 1 1 + 1x0 + 1)

1st line=5 2nd line=5 3rd line =3 add all lines= 13

1st line=5 2nd line=5 3rd line =3 add all lines= 13

50
5x5x2=50

Answer is 2
Duhh.......

THE ANSWER IS 30
Easy to see only 10% of people get this right, only by reading the comments. I had it wrong also. I had 12, the easy answer.
But thats wrong, there are no + signs in between each line, which makes it + 11, not + 1. You cant just assume there is a + sign between each line. This is math, you cant assume anything.

Cherrs

So if u say there's an 11, then why aren't u countinf them both?

I did. Thats how you get to 30...
Pretty straight forward once you get the catch of the ''11'''s. P

A mathematical conundrum where lateral thinking is useful. There is no right answer it's a matter of interpretation one would have to ask the person who set the question his intention. It's like the Delphic Oracle It just is.

Clowns! Its 13 you dumdass mothers! Why are you talking about 1x0 shit? The x0 is at the end before the +1! Idiots!

I'm a little disappointed in the second one because it's way too specified. It'll only work in 2017 if you haven't had your northday yet and once 2018 arrives it will work for no one :(

I am a math professor and the answer is 12

U guys are idiots I'm in 5th grade and I know this more than u the answer to the first one is 0 because anything times 0 will equal 0 it is fact look it up if u dint BELIEVE me

I got 812 the last digit of my phone number is 8 but I'm not 12. I'm 13.

You guys it 12 PEMDAS!!! ORDER OF OPERATION!!!! 5th grader, it's 12, honey.

The answer is 12
You add all the 1s and the last 2 numbers are a separate sum that you times it by.
So 12 x 1 = 12

The answer is 12
You add all the 1s and the last 2 numbers are a separate sum that you times it by.
So 12 x 1 = 12

552
1+1+1+1+1=5
1+1+1+1+1=5
1+1*0+1=2

So the thing with the age and phone number, mine was wrong. 6 for my phone number was correct but 23 is wrong for my age.

The phone number thing did not work. I got 41 as my answer. Every time.

The two rows of 1's don't have an operator at the end, so they can't carry into the next row. The third row is subject to interpretation: is it
((1+1)×0)+1? If so, the answer is 1. Is it
1+(1×0)+1? Then the answer is 2. Or is it
(1+1)x(0+1)? If so, the answer is again 2.

The two rows of 1's don't have an operator (+, -, ×, ÷, =) at the end, so they can't carry into the next row, or even be an equation by themselves. The third row is subject to interpretation: is it
((1+1)×0)+1? If so, the answer is 1. Is it
1+(1×0)+1? Then the answer is 2. Or is it
(1+1)x(0+1)? If so, the answer is again 2.

You guys are all wrong is 22 and look at it it’s 9+11 = 20x0=20+1=21+1=22 There you’re welcome

9+11=20andThe reason why this 20×0 doesn’t become zero it’s because the plus sign take over the multiply Symbol you never Multiply you stay with 21+1=22 dam I’m good

For the second part, it doesn't say my age, it says an age that is 1 year younger than how old I am.

Disregard the first 2 rows of ones(1+1+1+1+1) as they are mathematical expressions and have no operation symbol to connect to the next expression below it.
Now you are left with 1+1x0+1=.
Order of operations Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Now 1+1x0+1=1+0+1=1+1=2

I GUESS MATH HAS CHANGED SINCE I WAS IN SCHOOL. WHEN I DO THE MATH SHOWN IN THE EQUATION ABOVE MY ANSWER IS 1. Adding all the numbers x 0 = 0+1=1. Whats wrong with me? Have I lost my mind inmy old age?

It didn’t work. I was left with a 2 digit number.

1 is the answer,not for any of the reasons you have said.1st line there is no sign at the End of the line or the beginning of the next line. I This is the same for line 2. On the 3rd line it is 1x and not 1 x so there is only 1 part and this is 0+1=1

1x0=0, then 0+1=1 so it's 1
