There are 6 and 7 rows each of cars parked in the front and back of the father's car parked in the parking lot, and 5 and 6 rows each of cars parked on either side and the number of cars in each row is the same. How many are there in all?
6 7 [OP_ADD] 1 [OP_ADD] 5 6 [OP_ADD] 1 [OP_ADD] [OP_MUL]
var_a = 6
var_b = 7
var_c = var_a + var_b
var_d = 1
var_e = var_c + var_d
var_f = 5
var_g = 6
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))
