Problem 1Objects, Names, and Assignment

Sum Then Multiply

Assume you are given three numeric variables a, b, and c (already defined for you). Create a variable named result that first adds a and b, and then multiplies that sum by c.

Be careful about operator precedence: the addition must happen before the multiplication.

a = 5
b = 3
c = 4

a = 5
b = 3
c = 4
