Question

Q. Add the following in three ways. Indicate the property used.
(a) 35 + 36 + 25
(b) 40 + 18 + 32

Answer 1

Answer:

35 + 36 + 25 = 96

Step-by-step explanation:

There can be 3 properties used they are Associate Property, Distributive Property, Commutative Property.

1. All these properties have addition and multiplication formula's.

2. In Distributive Property we use multiplication to find the sum.

3. The Purpose of using properties is the sum will be same but the method will be different.

With the given data, consider a = 35, b = 36, c = 25.

• Associate Property for addition - (a+b)+c = a+(b+c)  

   (35+36)+25 = 35 +( 36 + 25) ; which results in 96.

• Commutative Property with addition -  a+b = b+a
• Adding first 2 numbers or last 2 numbers is equal to the same result.                                                                                                              71 + 25= 25+ 71 ;   result is 96.

• Distributive Property with addition -   a(b+c)=ab+bc                                35(25+36)= 35×36+35×25;   The result is same as LHS and RHS, 2135.
