2<a<3
5<b<6
2-5 < a-b < 3-6
-3 < a-b < -3 , by the "sandwich concept"
a-b = -3
5<b<6
2-5 < a-b < 3-6
-3 < a-b < -3 , by the "sandwich concept"
a-b = -3

the largest a-b will be when the smallest b is subtracted from the largest a.
and the reverse for the smallest a-b. So,
2-6 < a-b < 3-5
-4 < a-b < -2
and the reverse for the smallest a-b. So,
2-6 < a-b < 3-5
-4 < a-b < -2
