40+40x0+1 =

A bear falls down a hole exactly 10 meters deep from a perfect standstill which takes exactly 1.6 seconds. What color is the bear?

Doesn't look right to me, even taking the range of mavity available 1.6 secs is too slow.

Looks like a failed Polar bear (white) puzzle.

Yeah it looks broken, here is a fixed one.
A ball falls from a cliff of height 491.5m in 10 seconds.What is the colour of the bear of that region?

I imagine I'm generating a fair bit of ire suggesting that bodmas is redundant in the face of a well written expression... And I'm being fairly bloody minded about that.

You would be wrong though as the "well written" bit would be using brackets to surround the 40x0 (i.e. 40+(40X0)+1). The act of using brackets means that you are going back to bodmas again. On a wider mathmatical scale it is also inefficient because you need to start putting brackets in where they are not specifically required.
 
Why is it 41? I got 81 lol

What have you done with the x0 in the expression? You appear to have simply ignored it.

If you're using BODMAS/BOMDAS/BIDMAS (Brackets, Operations/Indices, Multiplication, Division, Addition, Subtraction) as is conventional then due to the order of operations you'd do the multiplication part first so 40*0=0 which leaves a 40 and a 1 to add together. It might be clearer if you put in artificial brackets to separate terms i.e. 40+(40*0)+1 so the second step is 40+(0)+1 and then finally you get 41. Any clearer?

The expression is deliberately written to confuse people who don't follow or aren't aware of the rules and order of operations but when you know them it isn't all that hard to interpret.
 
I might have a really naive and narrow view of life but how can you not know this?

I understand stuff like trigonometry and integration will not be used by most people, but simple addition and multiplication?

How can someone think 80 x 0 = 80 :eek:
 
Well if you start with £80 and x by 0 you still have £80. However the 80 x 0 is actually expressed at 80 lots of nothing, then it makes sense.

Just like giving 110% which isn't possible, as percentage is out of 100

They aren't related. If you multiply something by 0 you have 0 of whatever it is. Regardless. £80*0 means you have 0 £80s, i.e. £0.

This worries me.

:eek: that's scary
 
Jay what job do you have?

Does it use any sort of maths?

No I'm a security guard, I can actually feel myself getting dumber lol

No, if you have £80 and ADD 0, you still have £80. If you have £80 and multiply it by 0, you have nothing. You are giving yourself 0 lots of £80 - in effect saying that your £80 doesn't exist.

EDIT: What you're thinking, I imagine, is what happens if you get a 0% rate of interest on your £80. In this case, what you are doing is as follows.

0 x 80 (ie rate of interest x your original amount)

PLUS

£80 (your original £80)

= £80
 
I think this thread actually has some merit, if someone can learn something new then that can't be a bad thing right?

Regarding multiplying by zero, consider the following three sums:

80 x 2
80 x 1
80 x 0

Hopefuly it seems sensible that these sums will give different results. Looking at the answers:

80 x 2 = 160
80 x 1 = 80
80 x 0 = 0

When you multiply anything by zero you always end up with zero.
