(-5) - 9 =

(-11) - 2 =

b)

3 - (-5) = 3 + 5 =

(-1) - (-4) =

(-9) - (-3) =

13 - (-7) =

Zad. 6. Oblicz:

a)

(-3) - (-7) =

8 - (-4) =

(-10) - 8 =

7 - 15 =

b)

(-3) - 10=

(-12) - (-6) =

(-9) - (-3) =

(-8) - 1 =

c)

11 - (-11) =

(-25) - (-25) =

(-34) - 50 =

(-42) - 40=

d)

(-40) - (-20) =

(-120) - 70 =

520 - (-20) =
