Odpowiedź:
Poziom C
a)
2 * [ 7 - ( 3 - 1)] = 2 * (7 - 2) = 2 * 5 = 10
b)
16 : [ 2 + 8 : (2 + 2)] = 16 : ( 2 * 8 : 4) = 16 : (16 : 4) = 16 : 4 = 4
c)
3 * [4 + 2 * (1 + 1)] = 3 * (4 + 2 * 2) = 3 * (4 + 4) = 3 * 8 = 24
d)
8 - [2 * (5 - 1) - 3 ] = 8 - (2 * 4 - 3) = 8 - (8 - 3) = 8 - 5 = 3
e)
10 + 2 * [ 3 + 2 : (1 + 1)] = 10 + 2(3 + 2 : 2) = 10 + 2(3 + 1) = 10 + 2 * 4 =
= 10 + 8 = 18
f)
[2 * (3 - 1) + 6 ] : 5 = ( 2 * 2 + 6) : 5 = (4 + 6) : 5 = 10 : 5 = 2
