This puzzle is driving us all crazy!!

Oh, I see what you mean.

As I say, I should have gone to Specsavers but it was postponed!
Other opticians are available.

I've counted 4 wristbands, 2 on wrists and 2in hands hanging down.
So, man=5, shoes=10, 4 wristbands=8 total=23.
2×23=46
Add 1 shoe =51.

If there were brackets, the answer could be different.

Top row: 6 trainers in total, so one trainer = 5

2nd row: 2 trainers = 10, so 20 - 10 = 10. Therefore 1 man = 5

3rd row: man is 5, so 13-5 = 8. Therefore each weight (4 in total) = 2

4th row: man is holding 2 weights and wearing 2 trainers. Therefore man is: 5 + 4 (2 weights) + 10 (2 trainers). So man equals 19.

Now we have the sum 5 (1 trainer) + 19 (man) x 2 (1 weight)
So 5 + 19 x 2 = 5 x 38 = 43 (Don't forget order of operations)

So the answer is 43

Marydoll, my problem solving strategy for teaching P.7 tricky maths was to work backwards at the dining table the night before!!

Good brain training, well done everyone for persevering, thank you Katek!

Oh, my, is that the time?

However, are we counting wristbands on his wrist or not?
I was, Marydoll

I make it 43

Trainer=5
Man=5
Strap=2

Bottom line: 5+10+4= 19x2=38+5=43

I can't see any brackets

Granmarie I thought he had stuck his wrists through and they were weights hanging down, so one on each wrist? ie 4?

A man (5) plus 2 shoes (10) plus 2 weights (4) = 19
x 2 = 38
+ 1 shoe = 43

Marydoll, thanks for showing the brackets, I didn't know how to do that

So, I'm going for (2×23) +5=51.

Now I've forgotten the width of the bed for my spare room! Back to work.

yes, I think they are weights which fit over the wrist

possibly

So sorry, I never saw this. I have just posted a different version of the same puzzle. Great minds think alike

Oh GM, remembering the horror of teaching tricky P7 maths has come back to torment me!

At least I could work back from the answer sheet if I was stuck!?

I don't think he is, he's wearing them and they're hanging down (I think)

I'm sure you're are right Grannmarie.

I didn't write it GGMK3, but I have taught it years ago as a problem solving activity to Primary 7 children!!

I couldn't remember the answer but I knew that the devil was in the details and BODMAS.

That's why I keep giving clues and suggestions, to help you towards the answer.

Oh I did realise he was wearing wristbands as well as carrying them???

If you follow Bodmas, the calculation should look like this.

So the multiplication should be done first, then add on the shoe.
However, are we counting wristbands on his wrist or not?

We had another version on our WhatsApp group- easier to see. Man is holding one each of the unknown objects in last line.

No that's wrong forgot a trainer!

1 trainer = 5 + 5(man) + 10(trainers he's wearing) + 4(straps he's wearing) = 24

24 x 2 (1 strap) = 48

I did have an optician's appointment but it was cancelled!

Do we agree that the man is wearing 2 shoes, 2 wristbands and holding 2 wristbands?

That equals 23. ?

43

Remember to multiply first...
yes, sorry, Granmarie is right
