አጠቃላይ የማባዛት መርህ

ለምሳሌ, ሀ ⋅ ለ (እንደ “ጊዜ ለ” አንብብ) ማለት ቃላቶቹን ጠቅለል አድርገን እንገልጻለን። a, ቁጥሩ እኩል ነው b. የማባዛት ውጤት ምርት ይባላል።

ምሳሌዎች

2 ⋅ 6 = 2 + 2 + 2 + 2 + 2 + 2 = 12
(ስድስት ጊዜ ሁለት)
5 ⋅ 4 = 5 + 5 + 5 + 5 = 20
(አራት ጊዜ አምስት)
3 ⋅ 8 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24
(ስምንት ጊዜ ሶስት)

6 ⋅ 2 = 6 + 6 = 12
(ሁለት ጊዜ ስድስት)
4 ⋅ 5 = 4 + 4 + 4 + 4 + 4 = 20
(አምስት ጊዜ አራት)

(ሦስት ጊዜ ስምንት)
