Poziom A :
d) y = 2 * x = 2 * 4 = 8
e) y = x : 3 = 12 : 3 = 4
f) y = x - 7 = 8 - 7 = 1
Poziom B :
d) c = a * b = 6 * 2 = 12
e) c = a + b + 1 = 6 + 2 + 1 = 9
f) c = b/a = 6/2 = 3
Poziom C :
d) s = (p - 2)/(r + 2) = (4 - 2)/(2 + 2) = 2/4 = 1/2
e) s = (p² + 2)/(r + 1) = (4² + 2)/(2 + 1) = 18/3 = 6
f) s = 2 * (p - 4) = 2 * (4 - 4) = 2 * 0 = 0
