A gold star for a correct answer



10

or 28

(haven't looked at any other replies yet)

Ah, no I change my 14 to 11

Close but far away

2 + 1 + 1 x 7 = 10

10

I want a banana and a chocolate chip cookie now.

OP, how do you know the correct answer?
Is this out if a book or something with an answer included? What's the 'official' solution provided?

As many posters have pointed out, your answer depends on certain assumptions, the riddle does not have a single, definitive solution.

17

70

10

So you either want it written as (2+1+1)7 = 28 OR 2+1+(17) = 10

But it’s a lucky guess if you get that correct or not if that’s the case, there’s no intelligence involved because there’s no indication on what way you expect the sum to be done.

3 + 1 + 1x7 =11.

@rosegoldwatcher the clock is worth 2, not 3 in the question. First two clocks were 3 though

10. 100%

It isn’t a lucky guess. There’s a strict rule. No one needs to be “indicated” which way the sum is to be done, because there’s only one way it can be done - the one that gives 10 for an answer. The other suggestion is just wrong.

Doh!

I hate these type of puzzles - not good for the visually compromised!

To the posters who say BIDMAS wasn't a "thing" when they were at school... out of interest how old are you?

I think I've discussed this on MN before, but it seems it became popular in the 80s/90s. The principles it encapsulates have remained unchanged in normal algebraic convention for what must be centuries, but the use of BIDMAS in the classroom as a teaching tool is more recent. (I only remember coming across it in the 90s when I became a secondary school maths teacher).

At my grammar school in the 60s we did BMDAS (Bless My Dear Aunt Sally). So it was definitely around then.

cookie: 10
banana: 2
clock: 3

So 3+2+2x10= 25

11 - dots on biscuit, single banana, clock points to two (nit 3)

Oops 10 - didn't spot the multiply

2 + 1 + (1x7]

35

35?
