I am going to attach 15 pieces of colored tape, every 20 centimeters (cm) in length, overlapping each other by 5 centimeters (cm) in a long line. Find the total length in centimeters (cm) of the 15 sheets of colored tape.
20 20 5 [OP_SUB] 15 1 [OP_SUB] [OP_MUL] [OP_ADD]
var_a = 20
var_b = 20
var_c = 5
var_d = var_b - var_c
var_e = 15
var_f = 1
var_g = var_e - var_f
var_h = var_d * var_g
var_i = var_a + var_h
print(int(var_i))
