FB 'Math' problem.
 

Please show your work.

I apparently don't know how to do basic math...

Can't show my work, it's a wild guess

Ugh, 45/3 = 15.
21/3 = 7
12/3 = 4

Thus 15+7=19*7=133

Don't fall for these - the point isn't the math problem, it's harvesting users

109 ...don't have any work :D

There is an order for operations - you do multiplication and division first, then addition and subtraction, rather than simply doing the operations as they appear from left to right. So the answer is 109.

Some observations.
The image of the witch in the first row is not the same as in the last.
Not all of the broom images in the third row are the same.
The image of the wand in the second row doesn't match the image in the last row.


I promise not to harvest any users, and there isn't a link to FB (or anywhere else) in my post.

4+15×7
4+(15×7)
4+105
109

133 (no work..retired)

^^This. Everyone should delete FB.

Kind of interesting with its subtleties. Looks like:

The wand = 7 each
There's 4 brooms that = 12, so they = 3 each
The witch with the broom and wand = 15
A witch w/o the broom and wand = 5

Bottom line would be 3 + (5 x 14) = 73

Very good

...and that is why I am a chemist :-). Forgot about that pesky order of operations thing!

Exactly, in the third row the middle spoon is doubled up so that counts as 2X.

Last row the witch is missing the spoon (whose X needs to be added to the 1st row where she is holding it) and the wand is either doubled or tripled up.

It's a two part problem, find the differences and calculate the values accordingly then do the problem.

They can be fun if you like solving a puzzle but yes, harvesting. Best to just ignore or do offline if you are bored.

I 'like' this one. :D

Exactly, if you see something designed to either make you think you're smart (take this quiz, can you find the one item that's different, Can you figure out this problem, etc...) or list off places that you've been or your favorite stuff or take our quiz to find out how lovable you are or how cool you are or etc...., just ignore it.

There wasn't a link to follow for this one. Just a picture posted with 'friends' replying.

Not saying that this isn't for harvesting users... But it's not like the click bait quizzes I see.

If this is the way to solve it....

broom line has THREE brooms, not FOUR

Broom = 4
Wand = 7
Witch with Broom and wand = 15
Witch alone = 15-4-7 = 4

4 + (4 x 7) = 32

Isn't it 3 brooms=12, i.e. four each?

So the 'base' witch is 15-7-4=4 also?

Bottom line is 4+4x7=32

Maybe.

If you look closely, there appears to be a second broom behind the middle one, as well as a second wand in the last formula.

two wands in the last pic also. ;)

There's a second layer of complexity in it, which is pretty obvious when you look at it closely. It catches people not paying close attention. I credit 71T Targa for busting it wide open.

I go with RB except using his reasoning I come up with 17.

3 wands value each = 7
4 brooms value each = 3
Bottom row: 2 wands + 1 broom.

I can't see that, but I'm old and the picture is intentionally fuzzified.

How many brooms?

4. 2 and a double image.

This is correct..

The Question is http://forums.pelicanparts.com/uploa...1586332298.jpg

although there are times when "order of addition" is critical. Ever made emulsions?

This one is more challenging, but not too difficult:

Yep..lots of them in college. Liquor was cheap then. :)

You broke the second rule.

102

Breaks rule #3.

Has to be: 042

On the original question:

All 3 witches,X on the top row are carrying a star wand,Y and a broom,Z.
3X+3Y+3Z = 45
(assume addition, instead of a multiplier or a different symbol)

All 3 star wands are the same.
3Y=21
Star wand =7

There are actually 4 brooms in the third row. I didn't notice at first.
(assume addition, instead of a multiplier or a different symbol)
4Z=12
Broom= 3

Going back to the first line to find value of the witch, X:
45 - three wands(=21) - three brooms(=9) = 15. 15 divided by three witches is 5.
Witch = 5.

So 7 + 3 + 5 =15

042

Edit nm already answered.

Your numbers for the individual items is correct. However, there are 2 wands in final equation, and the later action is x not +.

So considering PEMDAS it's: 3+(5x14)=73

(Steve nailed in on post #11).

;)

I first got 102 until I re-read #3.
Eric is right. Again..

Good catch.
