Question

find the following uning by using properties of addition 25 +45+65​

Answer 1

Answer:

The sum of two numbers does not change if the order of the numbers is changed. This property is expressed by the following examples of addition.

(i) 5 + 7 = 12

7 + 5 = 12

The sum of 5 and 7 is the same as the sum of 7 and 5, i.e., 12

(ii) 64 + 19 = 83

19 + 64 = 83

The sum of 64 and 19 = 83 and also the sum of 19 and 64 = 83

(iii) 235 + 126 = 361

126 + 235 = 361

The sum of 235 + 126 = 361 and also the sum of 126 + 235 = 361
