There are 12 carnations. You gave one carnation to each of the two teachers. Then, you would like to distribute the remaining carnations to two teachers. How many ways are there?
12 2 1 [OP_MUL] [OP_SUB] 1 [OP_ADD]
var_a = 12
var_b = 2
var_c = 1
var_d = var_b * var_c
var_e = var_a - var_d
var_f = 1
var_g = var_e + var_f
print(int(var_g))
