When Eunji's classmates stand in 3 lines with the same number of students in each line, Eunji stands at the 3rd from the front and the 6th from the back. Find the total number of students in Eunji's class.
3 6 [OP_ADD] 1 [OP_SUB] 3 [OP_MUL]
var_a = 3
var_b = 6
var_c = var_a + var_b
var_d = 1
var_e = var_c - var_d
var_f = 3
var_g = var_e * var_f
print(int(var_g))
