Iskudhufasho

Xisaabin

Iskudhufasho (ingiriis: multiply) astaanta calaamada u ah (x) waa hab la iskugu dhufto lambarada tirada xisaabta. Iskudhufashadu waxay ka mid tahay afarta hab ee aasaaska xisaabta. Si ka duwan iskugeynta, kalagoynta iyo iskuqaybinta ayaa Iskudhufashadu waa isku-jeer laabka lambarada la isku dhufanayo. Tusaale ahaan, 2 lagu dhuftey (x) 3 wadarta iyo jawaabtu waa labo jeer laabka lambarka 3 oo ah (3 + 3 = 6). Sidoo kale, lambarka 6 haddii lagu dhufto 8 wadarta iyo jawaabtu waa lix-jeer laabka lambarka 8 taasi oo u dhiganta 8 + 8 + 8 + 8 + 8 + 8 = 48.

Labo tiro marka la isku dhufto wixii ka soo baxa waxaa loo yaqaanaa Wadar.

Tusaale ahaa:


3 x 5 = 15

Bedka maro 4.5m × 2.5m = 11.25m2; 4½ × 2½ = 11¼

Ku dhufasho (calaamad "×") xisaab ahaan waa taranka tiro ee tiro kale.



Sharciga Iskudhufashada

lambarka eber (0) tiro kasta oo lagu dhufto wadarta iyo jawaabta soo baxaysaa waa eber (0). Sidaas darteed sharciga iskudhufashada lambarka eber waa jawaab ah eber. Dhinaca kale, lambarka kow (1) tiro kasta oo lagu dhufto wax isbedel ah kuma imanayo, sidaas darteed lambar kow waa ismabedelaha iskudhufasho.
