Given :

Two numbers 25 and 17.

How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)

To Find :

How much larger is the sum of the given numbers as compared to their difference.

Solution :

Sum of given numbers, S = 25 + 17 = 42 .

Difference of given numbers, D = 25 - 17 = 8 .

The difference between S and D is, S - D = 42 - 8 = 34 .

Therefore, sum of the numbers is larger by 34 than in difference.
