Write algorithm to calculate sum and difference of any two numbers

(step 1 and 2 help clarify the rest of the steps)

first Declare 2 variables →a ,b.

input 2 variables a and b.

print sum=a+b.

print difference = a-b.

print product =a×b.

Step-by-step explanation:

Hope this helps a little :)

BEGIN

DECLARE VARIABLES X, Y

 INPUT VARIABLES X, Y

  READ X, Y

    PRINT SUM = X+Y

    PRINT DIFFERENCE = X-Y

END
