lets see how good you are at math!

[cammykool]

no one of my friends on Facebook can get this right

so? lets see wif android only owners can do it

5+5+5-5+5+5-5+5x0=

15?

 

[cammykool]

yes... you used order of operations

 

[Rxpert83]

The way I saw it... for those who had troubles. Multiplication goes first before addition/subtraction
5+5+5-5+5+5-5+5x0=
----------------------------
5+5+5-5+5+5-5+(5x0)=
5+5+5-5+5+5-5+(0)=
(5+5+5)-5+5+5-5+(0)=
(15)+(-5+5)+(+5-5)+(0)=
(15)+(0)+(0)+(0)=15

hm i understand i got it wrong too under the idea anything multiplied by 0 is 0

 

[Hadron]

Anything multiplied by 0 is 0. But multiplication is performed before addition and subtraction, so only the final 5 is zeroed that way.

May depend on how much programming you've done - although I prefer to use parentheses to make ordering unambiguous to the reader, as a coder operator precedence is something you consider automatically.

Holy crap ....when did this forum do school work (maths eww)

Man...I hate when my mom gets on the forums.

 

[jefboyardee]

My calc says 35, not that I expected it to. If I change it to:

5+5+5+5+5+5+5+789*0, I still get 35.

I hate math, it hurts my brain.

I think this whole "math thing" is just a fad anyway, it will be gone soon enough just like the internet & the cellularized telephone.

PEBCAC error....:rofl:

You replaced two -'s with +'s .....:bebored:

As a Brit, I haven't the foggiest idea what 9th grade actually is

I didn

I was right, but posting now seems pointless, as the answer was already posted...

On a side note, who *doesn't* like math!? It just works.
