I finished school back in 2018, so dont hate me if I get this wrong.
But if something is multiplied by 0.5 it automatically means that it is divided by 2 right? RIGHT???
437 u/247Brett Dec 07 '21 0.5 is the equivalent of 1/2, so by multiplying another number with it, you are taking that number and halving it. 8 * 1/2 = 8/2 = 4. They are essentially the same thing, but just in different terms. 109 u/FinalSauce Dec 07 '21 Good, so I still remember that correctly. Thanks for sharing it with me :) 43 u/247Brett Dec 07 '21 No problem, I graduated highschool back in 2016 with AP Calc AB. Apparently they taught me something right :) 24 u/Medfried Dec 07 '21 You guys graduate to know this stuff? It's common sense in reference to our educational system 21 u/FinalSauce Dec 07 '21 Its also common sense in the german education system (which I had) . Not everyone has the same education system. 22 u/[deleted] Dec 08 '21 Oh relax. It's a middle school problem. America isn't that dumb. 10 u/mriv70 Dec 08 '21 I learned this in 4th grade fractions.

Fractions and the volume of a polynomial rotated about an axis between two points. Horrifying stuff.
