so the above was posted on facebook, and i am absolutely floored by how many people get this wrong.

That’s what my sweet sister Tookie got, too, but she’s very math challenged so she assumed it was wrong.

For even more diverse results add in exponentiation and multiplication or division that relies on the correct order of operations.

Where'd that 'X' come from? Is this one of those quantum multidimensional internet thingamabobs that changes configuration every time you look at it?

88 + (2 x 33) = 154

I think it's 30.

Oops! Blew it the first time by not paying enough attention to what was there exactly.

New answer?

54

And once again, I still didn't pay enough attention!

3rd times the charm?

108

I royally suck at math, so I came up with 108. My method: Raincoat=2, boots=8 and gloves=3, so 2 boots (16) plus 1 raincoat (2) multiplied by 2 gloves (6) is 108.

5” of rain last night..

So
Put your rain coat on first
Then your wellies
Then your gardening gloves

As far as I'm concerned that's the right method...but you beat me, cuz you actually paid attention to how many of each were displayed in the last equation! Good job!!!

But, if I showed you a number 66, you wouldn't add them together. So I saw two boots as the number 88.

[Dave from down under]

Are the “1”s ones or sevens?

Are the gloves squared?
Or is a glove to the power of 3 gloves?

[bill_g]

The ones are ones. So, a coat plus a boot plus a boot is eighteen.

Ok, yeah, that makes sense. I saw it as 2 boots being twice the value of one boot, that's how I got 16 for that. That's one of the problems with equations like this - you have to know how the author was thinking.

What’s the go with gloves over gloves?

[bill_g]

Love at first sight I imagine. And it's cold outside.

What he said!

I think we all agree that one raincoat = 2, one boot = 8, and one pair of gloves = 3. So we have 2 boots + 1 raincoat * 2 pairs of gloves.
Subbing in values, that's 2*8 + 1*2 * 2*3. Many of you have implicitly followed the order of operations were it came to a group: parenthesis first. So let's use parentheses to better show the order of operations of the individual groups. (2*8) + (1*2) * (2*3) = 16 + 2 * 6. Multiplication/division comes before addition/subtraction, so let's put parenthesis around the multiplication to better show the next step. 16 + (2 * 6) = 16 + 12. Final addition step leaves us with 28, unless bootboot is actually 88 or other shenanigans.

Are the numbers 6, 18 and 14 or 6, 78 and 74? Former math teacher questions the penmanship.

The 6, 8, 4, and ? are all tilted to the right at the same angle as the 1, and the top line is not horizontal enough to be a 7. If it's a 7, it's extremely sloppy, and it looks like a typeface, not hand-lettered. 99%+ it's a 1.

[northland10]

Surprised how many times I missed there were 2 boots or 4 gloves, or there is a multiplication sign there, or that in a prior life I remembered stupid things like order of operations. Just so I can feel like a lush and not a total idiot, I'm blaming a 90 Minute IPA.

It's the standard European way of writing a '1'. Here is a discussion with example...
