Write two negative integers whose difference is 7.
There are number of possible solutions.
To find one of them, find the easiest combination of positive integers which when subtracted gives 7.
The easiest pair which comes to our minds are 10 and 3.
∵ 10 – 3 = 7
So, just subtract the negative form of these integers again.
⇒ Difference = -3 – (-10)
⇒ Difference = -3 + 10 [minus & minus = plus]
⇒ Difference = 7 [Since, 10 is greatest amongst 10 and 3, then + sign will appear in the resulting answer]
We have very carefully subtracted -3 from -10 rather than otherwise to get 7.
Thus, -3 and -10 are one of such pair of integers.
