Agree...Specially so graphically on figures set a task that everyone can feel like a Gaussian...

If I have a task to annoy your opponent, then I suggest him to play...He's using the calculator, and I mind much faster and without errors add up, subtract, multiply, divide, erected in the squares and remove the roots with six-digit numbers(up to a million !!!)...With particular cynicism this experiment I spend on the individuals of the fair sex...it directly produces stunning effect...They are so objaut after smart genius(that is me)...But can any fifth grader with 5 mathematics to teach such "art", but anyone naturally about this don't say...
