Crap. Just realized I had typed in the wrong equation last night. Got to tied up in making the text larger...

That should have been:

6÷2(1+2)=?

Is the answer 1 or 9?

wtf, how is it 9? I thought it was 1...

then again I forgot a lot of math skills. I can't do long division. I think we learned that in gr 4.

6÷2(1+2)=?





TS, you solve the division part first so 6 divided by 2 equals 3

then the addition portion....1+2=3

that gives you 3(3)...which is 3 multiplied by 3

if there had been a / instead of (), it would be 3 divided by 3 grin

happy did you use DMASBE to solve that. dont use most of it, but every once in a while use some geometry formulas, and ratios.

I can't remember what the proper names are for any of the theories or formulas...just how they work blushing


If that equation had been a few variables longer, I'd have been lost LOL

5 + 5 x 5 = ?

I thought the answer was 50.

I thought 5 + (5 x 5) = 30.

Do you read these left to right, but perform operations within a paren before the left to right string of operations?

"The sum of the square roots of any two sides of an
isosceles triangle is equal to the square root of
the remaining side."



Thanks Licks, after all this time I hadn't noticed the
reference to PEMDAS. Now I've got it!
