• x * (-1) ** 2 + 3 / (2 * x)

• x * (-1) ** 2 + 3 / 2 * x

• (x * (-1) ** 2 + 3) / 2 * x

Answer explanation

x * (-1) ** 2 + 3 / 2 * x

check the precedence rules,

** highest level

*, /

+ lowest level

so the order of operators are

(-1) ** 2 -> [1]

x * [1] -> [2]

3/2 -> [3]

[3] * x -> [4]

[2] + [4] -> (x*(-1)**2)+((3/2)*x)

• if x == 0:

• if x > 0:

• if x < 0:

• if x != 0:

Reorder the following to check a leap year as rules below

• Any year that is divisible by 400 is a leap year.

• Of the remaining years, any year that is divisible by 100 is not a leap year.

• Of the remaining years, any year that is divisible by 4 is a leap year.

• All the remaining years are not leap years.

• if year % 400 == 0:

  leap = True

• elif year % 4 == 0:

  leap = True

• elif year % 100 == 0:

  leap = False

• else:

  leap = False
