jeffygiraffe:fallopianrhapsody:haha fuck youIt’s actually a pretty simple question that just looks difficult.1) Look at what the fractions are - all the same, right? All are sevenths. So, you can multiply everything by 7 to get rid of the fractions. That gives you:8 + (-5) + (-2) = 02) Look at the +/- signs. When you have a + and a - together it makes a - sign. Bearing this in mind, the equation is essentially:8 - 5 - 2 = 0Which is incorrect because:8 - 5 - 2= 8 - 7= 1I just mean that I couldnt begin to do that kind of calculation in my head. I would need to write it down and literally visualize the problem with my eyes. -- source link
