Several children stand in a circle equally spaced apart. The 11th child and the 6th child are facing each other counterclockwise from one child. How many children are there in total?
11 6 [OP_SUB] 2 [OP_MUL]
var_a = 11
var_b = 6
var_c = var_a - var_b
var_d = 2
var_e = var_c * var_d
print(int(var_e))
