If a and b are positive, then a-b is positive identify the conclusion of the statement
Elanso [62]

Answer:

The statement is wrong. a-b can be positive but not always.

Step-by-step explanation:

There can be three possible situations that are:

  1. a>b
  2. a<b
  3. a=b

Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3

In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3

In the third condition, the result will always  be zero because both the integers will cancel each other. Such as 5-5=0
