Zad 1 - 4 5/7 trzeba odjac od 9 3/7 Zad2 A - (-3,4)+15/11+(-1,6)+7+(-1 4/5)= -3,4 + 1,3 + (-1,6) +7+ (-1,8)= 1,5 B - 4+(-1,125)+3 1/4+(-0,875)- 0,25 = -4 + (-1,125)+3,25 + (-0,875)- 0,25= - 2,75 C - -2 1/2-1,4+(-0,5)+10-0,6-(-10)= -2,5 - 1,4 + (-0,5)+ 10 - 0,6 (-10)= -5 D - -(-4)-(-5)-(-6)-11-(-(-4))= 4 + 5 +6 - 11 -4= 0 E - -11-16-(-10)+(-4)-[(-3)-(-4)] = -11-16-(-10)+(-4)- 1 = - 12 F - -[-(-5)-4-(-6)]-[-(-6)-4+(-10)] = -7 + 8 = 1 G - -{-[-(-4)-10}-[10-(-5)]}-(-5)= -9 + 5= -4

- 4 5/7 trzeba odjac od 9 3/7
Zad2
A - (-3,4)+15/11+(-1,6)+7+(-1 4/5)= -3,4 + 1,3 + (-1,6) +7+ (-1,8)= 1,5
B - 4+(-1,125)+3 1/4+(-0,875)- 0,25 = -4 + (-1,125)+3,25 + (-0,875)- 0,25= - 2,75
C - -2 1/2-1,4+(-0,5)+10-0,6-(-10)= -2,5 - 1,4 + (-0,5)+ 10 - 0,6 (-10)= -5
D - -(-4)-(-5)-(-6)-11-(-(-4))= 4 + 5 +6 - 11 -4= 0
E - -11-16-(-10)+(-4)-[(-3)-(-4)] = -11-16-(-10)+(-4)- 1 = - 12
F - -[-(-5)-4-(-6)]-[-(-6)-4+(-10)] = -7 + 8 = 1
G - -{-[-(-4)-10}-[10-(-5)]}-(-5)= -9 + 5= -4
