Paano mabilis at madaling matutunan ang multiplication table

Pagpaparami ay isang mathematical operation na maaaring katawanin bilang isang kabuuan ng magkaparehong termino.

Pangkalahatang prinsipyo ng pagpaparami

Halimbawa, ang a ⋅ b (basahin bilang "a beses b") ay nangangahulugan na isasama namin ang mga termino a, ang bilang nito ay katumbas ng b. Ang resulta ng pagpaparami ay tinatawag na produkto.

mga halimbawa:

• 2 ⋅ 6 = 2 + 2 + 2 + 2 + 2 + 2 = 12

  (anim na beses dalawa)

• 5 ⋅ 4 = 5 + 5 + 5 + 5 = 20

  (apat na beses lima)

• 3 ⋅ 8 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24

  (walong beses tatlo)

Tulad ng alam natin, mula sa permutasyon ng mga lugar ng mga kadahilanan, ang produkto ay hindi nagbabago. Para sa mga halimbawa sa itaas, lumalabas:

• 6 ⋅ 2 = 6 + 6 = 12

  (dalawang beses anim)

• 4 ⋅ 5 = 4 + 4 + 4 + 4 + 4 = 20

  (limang beses apat)

• 8 ⋅ 3 = 8 + 8 + 8 = 24

  (tatlong beses walo)

Mga praktikal na benepisyo

Salamat sa pagpaparami, maaari mong makabuluhang bawasan ang bilang ng kabuuang bilang ng mga item ng parehong uri, atbp. Halimbawa, kung mayroon kaming 7 pakete, bawat isa ay naglalaman ng 5 panulat, kung gayon ang kabuuang bilang ng mga panulat ay matatagpuan sa pamamagitan ng pagpaparami ng mga ito dalawang numero:

5 ⋅ 7 = 5 + 5 + 5 + 5 + 5 + 5 + 5 = 35

(limang panulat ng pitong beses)

Multiply sa 0
