When we let politics trump science, people are needlessly put in harm's way. http://arstechnica.com/science/2017/01/self-censoring-fears...
They're optimistic, glass half full kinda kids.
ReplyDeleteIt clearly should be 2/5...
ReplyDeleteStill optimistic^
ReplyDelete[spit take]
ReplyDeleteTotally going to fail that puzzle in KOTOR where you have to balance the tanks ...
ReplyDeleteI can totally follow what happened in the student's mind. Improper organization/notation in the solving, and reading his/her own work too quickly to catch the shortcut notation just executed.
ReplyDelete15/15 - 12/15 = 3/15 = 1/5
ReplyDeleteA new type of maths.
ReplyDeleteJoseph Milan Clearly if you remove the 1's from 12 and 15 you get 2 and 5 like the question says... take away 1 from 12 or 15... put the slash line or symbol back in there because it isn't part of what you need to take away and you are left with 2/5... 2 or 5.... simple.
ReplyDeleteEither that or the answer is 0.2
1 - 12/15 = 1 - 0.8 = 0.2
Hooray for New Math, Newwwwww Math. It won't do you a bit of good to review math. It's so simple, so very simple, that only a child can do it!

Now that I think on it...
ReplyDeleteThe answer is -11 or -14
1 - 12/15 = 1 - 12 or 1 - 15...
The real question is, can this be solved on Facebook?
ReplyDelete12/15 IS a fraction!!!
ReplyDeleteUnfortunately, Ray of Sunshine, that IS "showing their work"...it's just wrong.
ReplyDeleteRay of Sunshine 12/15= 4/5
ReplyDeleteWhen they reduced the fraction, they wrote it just like that.
Instead of continuing to figure out 1 - 4/5, they just saw the equals sign, stopped thinking, and moved on to the next problem. It's a lack of organization/structure, plus rushing.
15-12/15=1/5
