Multiplication is a mathematical operation of finding the result of two or more numbers by repeated numbers’ additions.
Multiplication is represented by the signs cross ‘×’, asterisk ‘*’ or dot ‘·’. When we multiply two numbers, the answer we get is called ‘product’. The number of objects in each group is called ‘multiplicand,’ and the number of such equal groups is called ‘multiplier’.
Example:
3 × 7 = 7 + 7 + 7 = 21
5 × 6 = 6 + 6 + 6 + 6 + 6 = 30
Here each group has 3 ice creams, and there are two such groups. So, there are 2 times 3 or 3 + 3 or 6 ice creams in total.
Properties of Multiplication
Commutative Property:
When we multiply two numbers, the order doesn’t matter. For numbers a and b,
a × b = b × a.
Associative Property:
For numbers a, b, and c, (a × b) × c = a × (b × c).
Distributive Property:
For numbers a, b, and c, a × (b + c) = (a × b) + (a × c).
