There are ........................ Pair of integers satisfying a/b=-1.
How many pairs of integers are there, satisfying the equation x2+y2=25?
for every pair of positive integers a and b there exist a unique pair of whole number q and r such that a=bq+r give examples of a and b whereever possible satisfying a) r=0 b) q=0 c) r>b d) if a< b what can be said about q and r
