a) 3 - 0 = 3
3 - 17 = -14
3 - (-4) = 3 + 4 = 7
b) -2 * 4 + 1 = -8 + 1 = -7
-2 * 0 + 1 = 1
-2 * (-3) + 1 = 6 + 1 = 7
c) 13-1/2 = 12/2 = 6
6-1/2 = 5/2 = 2 1/2
-6-1/2 = -7/2 = - 3 i 1/2
d) 2(1 - 3*0)/3 = 2/3
2(1 - 3*1)/3 = 2*(-2)/2 = -4/2 = - 1/2
2[1-3*(-1)]/2 = 2*4/2 = 8/2 = 4
Mam nadzieję że pomogłam i liczę na naj. ♥
