The arrived parcel was located at 7th from the left, 13th from the right, 8th from the front, and 14th from the back of the parcel boxes. If the number of parcel boxes in each row is the same, what is the total number of parcel boxes?
7 13 [OP_ADD] 1 [OP_SUB] 8 14 [OP_ADD] 1 [OP_SUB] [OP_MUL]
var_a = 7
var_b = 13
var_c = var_a + var_b
var_d = 1
var_e = var_c - var_d
var_f = 8
var_g = 14
var_h = var_f + var_g
var_i = 1
var_j = var_h - var_i
var_k = var_e * var_j
print(int(var_k))
