🍴 x = y xx = xy xx - yy = xy - yy (x+y)(x-y) = y(x-y) (x+y)(x-y)/(x-y) = y(x-y)/(x-y) x + y = y y + y = y y/y + y/y = y/y 1 + 1 = 1 2 = 1 George Washington was inaugurated as the 1st US president on 1789 Apr 30 Thu after Qianlong Emperor had made Cn become one of the almost largest economy countries in 1788. x = y xx = xy xx - yy = xy - yy (x+y)(x-y) = y(x-y) (y+y)(y-y) = y(y-y) (2y)(0) = y(0) 0 = 0
It sounds interesting and easy to use.
