  2. MnO`EwE • Presmetaj gi proizvodite: (-2 )(+7)(-5)(-3)= (-50)(-11)(-5)(+20)= (-7)(+8)(-4)(-125)= 2)Ako a=-5, b=+3 i s=-4 presmetaj: a) (a b) s b) a (b s) v) (a+ b) s g) a s+ b s • Presmetaj(-25+13)(-4), a potoa izvr{i proverka so koristewe na distributivnoto svojstvo.

  3. 4) Presmetaj: (-48)(+5)(-10) 0(-1999)= (+13)(-2)(+4)(+500)(-25)= (-1)(+1)(+125)(-9)= 5)Koristej}i gi znacite <,>ili=,sporedigi proizvodite: a) (+3)(-2)ili(+8)(-6); b) (+5)(-9)ili(-12)0 v) (+5)(-3)ili(-14)(+3) g) (-25)(-3)ili(+26)(-7) 6)Zapi{I go vo praznoto mesto znak~eto - ili + za da dobie{ to~en proizvod. a) (-3)(-12)= 36 b) (+26)(-25)= 650 v) (+9)(+25)= 225 g) (-18)(+15)= 270 d) (-36)(+12)= 432 |) (-14)(-40)= 560

  4. DeLeWe 1) Presmetaj: a) h:(-5)=-20 b) h:(+4)=-28 v) h:(-3)=-18 2)Presmetaj ja vrednosta na izrazite: -1-(-12):(+4)+(+2)= (+24):(-4)5):(-2)= 3)Koe tvrdewe e to~no a)Ostatokot pri deleweto ima ist znak kako delenikot. b)Ostatokot pri deleweto ima ist znak kako delitelot. v)Ostatokot pri deleweto ima ist znak kako koli~nikot.

  5. 4) Presmetaj go nepoznatiot mnozitel h ako: a) h:(-7)=+6 b) h:(+205)=-1 v) h:(-38)=-15 5)Presmetaj ja vrednosta na izrazot (2a-b)c-a za a=-12 b=+20 s=-5. 6) Zbirot na broevite -51 i +13 podeligo so brojot -19.
