#POPCORN HACK 1

def output(x):
    result = 2 * (x + 3) - 2
    print(result)

output(5)

14

#POPCORN HACK 2

number1 = 8
number2 = 3
number3 = number1 % number2
number4 = number3 * number1 + 70
print(number4)

#Remainder of 8/3 is 2
#2 times 8 is 16
#16 plus 70 is finally 86

86

#POPCORN HACK 3

numbers = [23, 25, 53, 69, 42, 90]


for num in numbers:
    remainder = num % 3
    if remainder == 0:
        print(f"{num} is divisible by 3")
    else:
        print(f"The remainder when {num} is divided by 3 is {remainder}")

The remainder when 23 is divided by 3 is 2
The remainder when 25 is divided by 3 is 1
The remainder when 53 is divided by 3 is 2
69 is divisible by 3
42 is divisible by 3
90 is divisible by 3

calculate_area()

Enter the term number for the Fibonacci sequence: 7
The 7th term in the Fibonacci sequence is: 13
Enter the shape (circle, square, rectangle): circle
Enter the radius of the circle: 7
The area of the circle is: 153.93791
