Suppose several monsters are trying to attack. If you shoot 4 times at a monster, 3 shots remain, and if you try to shoot 5 times, then you lack 6 shots. How many monsters are there?
3 6 [OP_ADD] 5 4 [OP_SUB] [OP_DIV]
var_a = 3
var_b = 6
var_c = var_a + var_b
var_d = 5
var_e = 4
var_f = var_d - var_e
var_g = var_c / var_f
print(int(var_g))
