you're not that great at maths
there isn't a correct option for the secound question!
2x(7y-1x)-9z(1y+6z) = 14xy-2x^2-9yz-54z^2
-9 times 6 is -54!!!!!!!! and just to let you know, i've just turned 13, which should say something about your so called "math skills". and in case your were wandering: ^ means to the power of.
Well...
I got passed the first 2 questions, then I didn't feel like doing the 3rd because I figured there would be either multiple right answers or none.
1st problem: There is more than one right answer but only one of them works.
2nd problem: None of the answer selections are right. The last number in each line of numbers should be -54. No positives.
very dissapointing
I think it's okay to do a math quiz now and then, but, like everyone else reviewed) 1 correct choice and 3 wrong . I haven't yet gone further then 2. But the first one had only one (or if you like) 2 incorrect answers. And the second were all wrong (-9z*+6z=! +5z)
oh, changing order might give different result, according to which commutativity you define... ;)
omg
this sucked and that screaming noise is really annoying.
Too hard wah
I could work the problems out on paper but I am here to see graphic intense fbf violent randomness with tits and such. I only got to second question a and d are the same answer but a is the correct one. The scream is annoying or some.
