I study in class 6 . my question is Write all the properties of whole numbers of addition and multiplication.
Answers
Answer:
1) Closure for addition and multiplication.
2) Commutative property for addition and multiplication.
3) Associative property for addition and multiplication.
4) Distributive property of multiplication over addition
Closure property :
5 + 6 = 11
9 + 8 = 17
2*3=6
Commutative property for addition and multiplication
You can add whole nos. in any order. We can say that addition is commutative for whole numbers. This property is known as commutativity for addition.
5 + 11 = 11 + 5
5*2=2*5
Associative of addition and multiplication :
Observe the following examples :
(5 + 7 ) + 3 = 12 + 3 = 15
5 + ( 7 + 3) = 5 + 10 = 15
Multiplication is true for associative property.
8 x 125 x 1294
Here , if you multiply 125 and 1294 then it will be hard and time consuming. So we will multiply 8 and 125 and then with 1294.
( 8 x 125) x 1294
= 1000 x 1294
= 1,294,000 This arrangement of number is known as associative property.
Distributive of multiplication over addition
35 x ( 98 + 2 ) = 35 x 100 = 3500
65 x (48 + 2) = 65 x 50 = 3250
297 x 17 + 297 x 3 = 297 x (17 + 3) = 297 x 20 = 5940
