When I arranged a few small square tiles without gaps to make a large square, there were 20 tiles left, so I tried to extend each horizontal and vertical side by 1 row to make a larger square, an there were 9 tiles short. How many tiles are there?
20 9 [OP_ADD] 1 [OP_SUB] 2 [OP_DIV] 2 [OP_POW] 20 [OP_ADD]
var_a = 20
var_b = 9
var_c = var_a + var_b
var_d = 1
var_e = var_c - var_d
var_f = 2
var_g = var_e / var_f
var_h = 2
var_i = var_g ** var_h
var_j = 20
var_k = var_i + var_j
print(int(var_k))
