Answer:
The pseudocode is as follows:
Input num1, num2
input operator
print num1 + num2
print num1 - num2
print num1 * num2
if num2 != 0
print num1 / num2
else
print "Cannot divide by 0"
Explanation:
This gets input for both numbers
Input num1, num2
This gets input for the operator
input operator
This prints the sum
print num1 + num2
This prints the difference
print num1 - num2
This prints the product
print num1 * num2
This prints the division if the divisor is not 0
<em>if num2 != 0</em>
<em> print num1 / num2</em>
<em>else</em>
<em> print "Cannot divide by 0"</em>

It would be an open source operating system. there isnt much to say but that is something that is more commonly known. so i honestly cannot provide a proper explanation for that
