गुणाकार हे एक गणितीय ऑपरेशन आहे ज्याला समान संज्ञांची बेरीज म्हणून प्रस्तुत केले जाऊ शकते.

गुणाकाराचे सामान्य तत्व

उदाहरणार्थ, अगोदर निर्देश केलेल्या बाबीसंबंधी बोलताना a ⋅ b (“a times b” म्हणून वाचा) म्हणजे आपण अटींची बेरीज करतो a, ज्याची संख्या समान आहे b. गुणाकाराच्या परिणामास उत्पादन म्हणतात.

गुणाकार सारणी पटकन आणि सहज कशी शिकायची

उदाहरणे:

  • २ ⋅ ६ = २ + २ + २ + २ + २ + २ = १२

    (सहा वेळा दोन)

  • ५ ⋅ ४ = ५ + ५ + ५ + ५ = २०

    (चार वेळा पाच)

  • ३ ⋅ ८ = ३ + ३ + ३ + ३ + ३ + ३ + ३ + ३ = २४

    (आठ वेळा तीन)

आपल्याला माहित आहे की, घटकांच्या स्थानांच्या क्रमपरिवर्तनातून, उत्पादन बदलत नाही. वरील उदाहरणांसाठी, हे बाहेर वळते:

  • ६ ⋅ २ = ६ + ६ = १२

    (दोन वेळा सहा)

  • ४ ⋅ ५ = ४ + ४ + ४ + ४ + ४ = २०

    (पाच वेळा चार)

  • 8 ⋅ 3 = 8 + 8 + 8 = 24

    (तीन वेळा आठ)

व्यावहारिक लाभ

गुणाकार केल्याबद्दल धन्यवाद, तुम्ही समान प्रकारच्या वस्तूंच्या एकूण संख्येची संख्या लक्षणीयरीत्या कमी करू शकता, इ. उदाहरणार्थ, जर आमच्याकडे 7 पॅकेजेस असतील, ज्यामध्ये प्रत्येकामध्ये 5 पेन असतील, तर त्यांचा गुणाकार करून एकूण पेनची संख्या सापडेल. दोन संख्या:

५ ⋅ ७ = ५ + ५ + ५ + ५ + ५ + ५ + ५ = ३५

(पाच पेन सात वेळा)
