Answer:
Addition
Step 1: Input the two numbers, a and b.
Step 2: Output a + b.
Step 3: Output a - b.
Step 4: Output a * b.
Step 5: If b = 0 output “undefined”.
Step 6: Else output a / b.
subtraction
Step 1 If ( a < b ) then there will be no answer .
step 2f ( a = b ) then all the numbers greater than a are the answer so there will be infinite solutions possible.
Step 3 If ( a > b ) Suppose x is an answer to our equation. Then x divides (a – b).
