A = (3/4)^2
A = 3^2/4^2
A = 9/16
B = (1 - 5^2)/(1 - 5)^2
B = (1 - 25)/(-4)^2
B = (-24)/16
B = (-8 x 3)/(8 x 2)
B = -3/2
E = (1/2 - 3/4) x 16/9
E = (2/4 - 3/4) x 16/9
E = (-1/4) x 16/9
E = -16/4 x 1/9
E = -4/9
F = 1/2 - 3/4 x 16/9
F = 1/2 - 3/9 x 16/4
F = 1/2 - 1/3 x 4
F = 3/6 - 4/3
F = 3/6 - 8/6
F = -5/6
