Explain that which statement is always true.

Answer to Problem 48STP
The option A is always true.
Explanation of Solution
Given:
The given statements are
A .Positive
B negative
C negative
D positive
Calculation:
Option A is always true, the positive number subtracted by negative number, the result will be always positive, because the subtraction process change into addition.
Example
Take a positive integer
And a negative integer
Difference
Use the following rules and find the result of the given expression.
Now,
Add two numbers with the same sign, the result has that same sign.
So,the result is also positive.
Hence the option A is always true.
