The sum of the lengths of the four sides of a parallelogram ABCD is 14 centimeters (cm). If the length of side AD is 5 centimeters (cm), how many centimeters (cm) is the length of side AB?
14 2 [OP_DIV] 5 [OP_SUB]
var_a = 14
var_b = 2
var_c = var_a / var_b
var_d = 5
var_e = var_c - var_d
print(int(var_e))
