I copied the post from Facebook so not sure why is mentions Americans?

Anyway, can you solve it

division by zero is invalid....

so the sum itself

to be valid (and obey the BODMAS rule of mathematical priority ) and thus make sense it needs re writing as

5+3x2-10/ (0+10)

in which case the answer is 0.1

becasue

according to the rules

we have 5+ (3x2) -10/(0+10)

so you work out the top of the division first

then work out the divisor

then do the division

multiplication has priority over addintion

hence

5+(3x2) is 11

NOT (5+3)x2 which is 16

so the sum itself

*as presented*is nonsensical....to be valid (and obey the BODMAS rule of mathematical priority ) and thus make sense it needs re writing as

5+3x2-10/ (0+10)

arguably so zack...but only if you do the maths WRONG and have an active division by zero...

you have to mensurate both top and bottom of the divison FIRST

so you dont actually have division by zero

since 0+10 = 10

and mathematically speaking infinity is undefined....

This is an ongoing argument on Facebook

Lots of people saying 21 infinity??

yes, but....

since infinity is undefined, the answer means you have your "mathematical model" wrong.

Yeah, my first thought was that there's never been a human being who has been able to solve that problem, since division by zero is impossible -- don't know why Americans were singled out.

Here's one -- a man sees his friend on the opposite side of a river and crosses over to greet him. He doesn't have a bridge or boat, but he doesn't get wet. How did he do it?

pretty sure it is 10.

10

5 + (3*2) - ------- = 5+6-1 = 10

(0+10)

10

5 + (3*2) - ------- = 5+6-1 = 10

(0+10)

@Zack

human error in the writing of the algorthm.

IF I was given that as computer typed Notes i would automatically assume the Division(/) is meant as a Fration marker.

so it would be 10 / (0+10) which is 10/10 which is 1

10/0 is irrational number so you cannot use it in a standard formula. thus assumption must be that is not what is implied.

notice to make the fraction look normal they loaded them as imagesARITHMETIC INVOLVING ZERO

If you add zero to or subtract it from any other number that number does not change,

e.g. 2 + 0 = 2, 6 – 0 = 6, 0 + ½ = ½ .

If you multiply by zero, the answer is always zero,

e.g. 5 ´ 0 = 0, 10000 ´ 0 = 0,

0 ´ = 0, (-6) ´ 0 = 0.

If zero is divided by another number the answer is zero,

e.g. 0 ¸ 6 = = 0.

You can NEVER DIVIDE BY ZERO

e.g. and are all undefined.

Or he walks around a bend in the river ?
