Question

If a+b =b+a? give reason...

Answer 1

Answer:

commutative property of addition

Step-by-step explanation:

This is called as the commutative property of addition. This property says, when the order of numbers are changed, the sum of these two numbers remains the same. For example 3 + 6 = 6 + 3. here both sum are equal to 9 even though they are written in opposite sides. This applies to any number of terms but the sum is always the same. We can consider for example

3 + 2 + 4 + 5 = 5 + 4 + 3 + 2.  

14 = 14. The sum remains same but only the order of numbers are changed. We can have any items in any order but the quantity does not change.

Answer 2

To find:

Is a + b = b + a true or not.

Solution:

Commutative property over addition:

a + b = b + a

i.e. if you add numbers in any order, it gives the same answer.

Let us check using examples.

5 + 10 = 15

10 + 5 = 15

So, 5 + 10 = 10 + 5

Hence a + b = b + a is true.
