Just when I thought I was getting better at math...

made me scratch my head.


7 + 7 divided by 7 +7 x7 -7.

The correct answer is apparently 50.

IF you do it this way: 7+7 =14 divided by 7 =2
2 +7 = 9, 9* 7 =63, 63-7 = 56.

If you do it by calculator = 56

If you do it by Excel = 50

Apparently it is supposed to be 7x7= 49 /7 = 1, then 1+7+7 -7 = 8.
Which still makes no sense. So, it must be = 7x7/7 =1, then 7+7+7 =21 +1
Still makes no sense. I remain puzzled.

This is why I hate math.

There is no thirtieth dollar.

Each Salesman paid $9. $10 spent, with $1 returned as change) $25 of those dollars went to the hotel, and $2 went to the Bellboy.

The text of the last sentence makes it appear as if the 2 dollars should be added to the 27, when it is actually split out....

I know, but it sounds like it makes sense... It's a deliberate mislead.

Explains why mathematical word problems always confused me. ;-)
