Stuck? The idea behind arithmetic
input() always gives text: turn it into a whole number with int() or a decimal with float() before doing sums.
+ - * / work as in maths; / always gives a decimal. // divides and drops the remainder, % gives the remainder, ** raises to a power.
a = int(input()) b = int(input()) print(a + b) print(a // b, a % b)
Watch for: "5" + "3" is "53", not 8: if a sum joins numbers together, an int() is missing.
