There are pieces of ribbon each of which is 30 centimeters (cm) long. I tied 15 pieces of ribbon to each other to make a long piece of ribbon. If 2 centimeters (cm) of a piece of ribbon is used to tie the ribbon, what is the length of the piece of ribbon made?
30 15 [OP_MUL] 15 1 [OP_SUB] 2 [OP_MUL] [OP_SUB]
var_a = 30
var_b = 15
var_c = var_a * var_b
var_d = 15
var_e = 1
var_f = var_d - var_e
var_g = 2
var_h = var_f * var_g
var_i = var_c - var_h
print(int(var_i))
