Question

In order to compute 25 + 36 + 35, which two numbers should be added first?

• A. 25 , 35
• B. 25 , 36
• C. 36 , 35

Answer 1

The correct option is A 25 , 35

For addition of more than two numbers, it is preferred to start by adding the two numbers that give a number ending with 0 as the result.

25 + 36 + 35 = (25 + 35) + 36
[25 and 35 are associated because 5 + 5 = 10]
= 60 + 36 = 96
