  1. ABECEDA RAČUNALA BINARNI RAČUN 1+1=10 predavač:

  2. Binarne znamenke 0,1 ?

  3. 1 0 0 1 1 1 0 1 1 Koliko je ? 10011(2) + 1011(2) 1 1 Binarno: 1 + 1 + 1 = 11 + 1 1 1 1 0 10011(2) + 1011(2) =11110(2)

  4. Binarne znamenke 0,1 Binarno MNOŽENJE

  5. 1 0 0 1 Koliko je ? 1001(2)·101(2) · 1 0 1 0 1 0 0 1 + 1 0 1 1 0 1 1001(2)·101(2)=101101(2)

  6. Binarno ODUZIMANJE Koliko je ?1110101(2) -1001(2) 1 1 1 0 1 0 1 1 0 0 1 - 1 1 0 1 1 0 0 1110101(2) -1001(2) =1101100(2).

  7. Binarno ODUZIMANJE Oduzimanje svodimo na zbrajanje: a-b = a+(-b). U binarnom brojevnom sustavu negativni brojevi predočavaju se dvojnim komplementom. Koliko je ?1110101(2) -1001(2) Postupak: Umanjitelju s lijeve strane dopišemo nule (ako je potrebno) tako da umanjenik i umanjitelj imaju jednak broj znamenki. 1110101 0001001 Odredimo komplement umanjitelja (umjesto 0 pišemo 1 i obrnuto) 1110110 Komplementu pribrojimo 1 + 1 1110111 • - dobili smo dvojni komplement Dvojni komplement pribrojimo umanjeniku te odbacimo krajnju lijevu jedinicu. 1110101 + 1110111 11101100 1110101(2) -1001(2) =1101100(2).

  8. Binarno DJELJENJE ? Uzastopno oduzimanje!

  9. Što smo naučili? Zbroji, oduzmi i pomnoži brojeve: 1000111(2) i 1011(2) • PROVJERI DOBIVENE REZULTATE DEKADSKI!
