Simple arithmetics

Don't you hate parenthesis in large calculus? The way in which you have to take care of not doing the operations in the wrong order? This student decided that he didn't care.


Hey! There's even a small smiley down there, ":-6"! And guess what there isn't down there? A result!

Cube roots and simplified fractions

Anybody whith a minimal mathematical formation, even 10-year-olds, know that 4/8 = 1/2, and that 10/100 equals 1/10. Similarly, one tends to believe that the cube root of a number bigger than 1 is supposed to be smaller than that number.

Well, this guy doesn't


Now, for those of you who didn't already saw it, I'll point you to the end of the image, to see one of the greatest simplifications methods ever: dividing by 10_0 ! What? Did you never hear about it? It's the same as dividing by 100, but with a space in the middle! And it only affects the numbers you want, not necessarily the entire fraction! And what is more, you don't even have to bother to do the subtractions correctly! Just write 15-59=39, and you're done!

Advanced equation solving

Most of us kow how to solve a 1st degree equation with only one variable. It's pretty simple, but it can be tedious. With this guy's method, we can "solve" it much faster:


How could we have been so blind for all this years? All we needed to do was to eliminate the = sign, and everything becomes much simpler!

...Although, what does "x 4" means? x=4? x=4x? x and 4 are friends and that's why they live together inside a badly drawn rectangle? I really don't know, but that's probably due to the high level of math knowledge that this equation method solving requires...
