math help

Where do parentheses go to make this equation work? 9+12/3+4/2+1x2=12
x=multiplication(not a variable)
/=division(couldn’t figure out what else to use for it)

Greatly appreciated:D

I’m confused. This string does not equal 12.

Well, if you bear in mind the fact that your answer ‘12’ is a whole number, that eliminates a couple of possibilities…

If you then consider what you need to add to ‘9’ to get to ‘12’, well, there’s your answer !

don’t thank me, just trying to help the community

9+12/(3+4/(2+1x2))
= 9+12/(3+4/4)
= 9+12/4
= 12

9+(12/(3+(4/(2+(1x2)))))=12

The way the equation is written it doesn’t equal 12. I need to know where you add parentheses in the equation so that it will equal 12. Like this, 9+12/3+4/2+1x2=8. Add parentheses in it like this, ([9+12]/3)+4/(2+[1x2])=8 and it becomes true. I need to know where in 9+12/3+4/2+1x2=12 you add parentheses/bracets to make the equation true and equal to 12.

Any help with this would be greatly appreciated. I’m stumped :frowning:

While I was typing up that last post it seems someone has answered it. Heh, so disregard my last post there. And again, thank you loads for the help :slight_smile:

And both Orbifold and davidm have shown you how to do it.

Well, now you can obviously disregard my last post as well.

Doesn’t anyone preview anymore? Think of the hamsters’ children!
