Daabacaaddan, waxaanu tixgelin doonaa 8 sifo oo aasaasi ah oo qaybinta tirooyinka dabiiciga ah, iyaga oo la socda tusaalooyin si loo fahmo maaddada aragtida.
Guryaha qaybinta tirada
Hanti 1
Tirada qaybinta nambarka dabiiciga ah lafteedu waxay la mid tahay hal.
ah: a = 1
tusaalooyin:
- 9:9 = 1
- 26:26 = 1
- 293:293 = 1
Hanti 2
Haddii tirada dabiiciga ah loo qaybiyo mid, natiijadu waa isku mid.
ah: 1 = a
tusaalooyin:
- 17:1 = 17
- 62:1 = 62
- 315:1 = 315
Hanti 3
Marka la qaybinayo tirooyinka dabiiciga ah, sharciga gudbinta lama dabaqi karo, kaas oo ansax ah .
ah: b ≠ b: a
tusaalooyin:
- 84:21 ≠ 21:84
- 440:4 ≠ 4:440
Hanti 4
Haddii aad rabto inaad u qaybiso wadarta tirooyinka tiro la siiyay, markaa waxaad u baahan tahay inaad ku darto tirada qaybinta qoraal kasta oo lambar la siiyay.
Hantida dib u celi:
tusaalooyin:
(45 + 18): 3 =45: 3 + 18: 3 (28 + 77 + 140): 7 =28: 7 + 77: 7 + 140: 7 120: (6 + 20) =120: 6 + 120: 20
Hanti 5
Marka aad u qaybinayso faraqa nambarada tiro la siiyay, waxa aad u baahantahay in aad ka jarto tirada kala qaybinta nambarka la siiyay kana soo goyso minuend nambarkan.
Hantida dib u celi:
tusaalooyin:
(60 – 30): 2 =60:2-30:2 (150 – 50 – 15): 5 =150: 5 - 50: 5 - 15: 5 360: (90-15) =360:90-360:15
Hanti 6
U qaybinta wax soo saarka nambarada mid la siiyay waxay la mid tahay in la qaybiyo mid ka mid ah qodobbada tiradan, ka dibna lagu dhufto natiijada mid kale.
Haddii tirada lagu qaybsanayo ay la mid tahay qodobbada midkood:
- (a ⋅ b): a = b
- (a ⋅ b): b = a
Hantida dib u celi:
tusaalooyin:
(90 ⋅ 36): 9 =(90: 9) ⋅ 36 =(36: 9) ⋅ 90 180: (90 ⋅ 2) =180: 90: 2 =180: 2: 90
Hanti 7
Haddii aad u baahan tahay tirada qaybinta tirooyinka a и b nambar u qaybi c, taas macnaheedu waa a loo qaybin karaa b и c.
Hantida dib u celi:
tusaalooyin:
(16:4) :2 =16: (4 ⋅ 2) 96: (80: 10) =(96: 80) ⋅ 10
Hanti 8
Marka eber loo qaybiyo tiro dabiici ah, natiijadu waa eber.
0: a = 0
tusaalooyin:
- 0:17 = 0
- 0:56 = 56
Fiiro gaar ah: Nambar kuma qaybin kartid eber.
