a = 2 + (2 : 2 + 2 x 2)
b = 1 + 2 x (3 + 4)
c = 1893 - 3 x (719 -699)
Rezolvare
a = 2 + (2 : 2 + 2 x 2)
a = 2 + (1 + 4)
a = 2 + 5
a = 7
b = 1 + 2 x (3 + 4)
b = 1 + 2 x 7
b = 1 + 14
b = 15
c = 1893 - 3 x (719 -699)
c = 1893 - 3 x 20
c = 1893 - 60
c = 1833
Suma este
2 x a + 3 x b + 10 x c
2 x 7 + 3 x 15 + 10 x 1833
14 + 45 + 18330
59 + 18330
18389
