Question

If a and b are two integers such that a is the predecessor of b, then find the value of a_b

Answer 1

a-b= -1

Explanation:

according to the question,

a is the predecessor of b , it means a is before number of b

a and b are both integers

Let a =9

b= 10 (as a is predecessor i.e -1 of b)

a-b =9-10 => -1

hence a-b = -1
