Hoseok is always 4th from the left and 9th from the right in a row. How many students are there if there are 5 lines every time they jump rope and the number of students in each line is the same?
5 4 9 [OP_ADD] 1 [OP_SUB] [OP_MUL]
var_a = 5
var_b = 4
var_c = 9
var_d = var_b + var_c
var_e = 1
var_f = var_d - var_e
var_g = var_a * var_f
print(int(var_g))
