On the first day of participating in the group activity, Miju met 11 new friends and shook hands. If Mijoo and her friends shook hands once, how many times did they all shake hands?
11 1 [OP_ADD] 11 [OP_MUL] 2 [OP_DIV]
var_a = 11
var_b = 1
var_c = var_a + var_b
var_d = 11
var_e = var_c * var_d
var_f = 2
var_g = var_e / var_f
print(int(var_g))
