Question

Give the output of the following when num1 = 4, num2 = 3, num3 = 2.

num1 = 2 + 9 * ((3 * 12) - 8)/10
print(num1)

Answer 1

num1 = 2 + 9 * ((3 * 12) - 8)/10

# The expression within inner brackets will be evaluated first

num1 = 2 + 9 * (36 - 8)/10 

# The expression within outer brackets will be evaluated next

num1 = 2 + 9 * 28/10

# * and / are of the same precedence, hence, left to right order is followed

num1 = 2 + 252/10

num1 = 2 + 25.2

num1 = 27.2

Therefore, the output will be 27.2.
