Class 6 - Mathematics - Unit 3: Integers - True or False Questions

Question 39

1. We need three different integers whose sum is 0.
2. Take the numbers: −1, 0, 1. All three are different.
3. Write their sum:
   ( -1 + 0 + 1 )
4. Add the first two:
   ( -1 + 0 = -1 )
5. Now add the third number:
   ( -1 + 1 = 0 )
6. The sum is 0 and the numbers are different. So the statement “The sum of three different integers can never be zero” is false.

Another example:
( -2 + (-1) + 3 = -3 + 3 = 0 )
