I made a rectangle by arranging 4 Go stones horizontally on each row and 8 vertically on each column. How many Go stones are at the perimeter?
4 8 [OP_ADD] 2 [OP_MUL] 4 [OP_SUB]
var_a = 4
var_b = 8
var_c = var_a + var_b
var_d = 2
var_e = var_c * var_d
var_f = 4
var_g = var_e - var_f
print(int(var_g))
