zad 2
a) 7 * ( - 6) - 20 = - 42 - 20 = - 62
b) 50 - 3 * 9 = 50 - 27 = 23
c) 10 * 2 + 2² = 20 + 4 = 24
d) (- 5)² - 4 * (- 5) = 25 + 20 = 45
e) 2 * 1³ + 3 * 1 = 2 + 3 = 5
f) 4 * 1/2 - 2 = 2 - 2 = 0
zad 3
a) 5 * (- 4) + 7 * 3 = - 20 + 21 = 1
b) - 2 * ( - 8) - 6 * ( - 2) = 16 + 12 = 28
c) 2* ( - 1)² + 3 * ( - 5) = 2 * 1 - 15 = 2- 15 = - 13
d) - 5 * ( - 4)² - 9 * 0 = - 5 * 16 - 0 = - 80
e) 10 * 2² - 7² + 7 = 10 * 4 - 49 + 7 = 40 - 49 + 7 = - 9 + 7 = - 2
