I am trying to put 7 posters on a wall that is 20 meters (m) wide. The posters were pasted at equal intervals, starting at 1 meter (m) apart from each end of the wall. Find the space between the posters.
20 1 2 [OP_MUL] [OP_SUB] 7 1 [OP_SUB] [OP_DIV]
var_a = 20
var_b = 1
var_c = 2
var_d = var_b * var_c
var_e = var_a - var_d
var_f = 7
var_g = 1
var_h = var_f - var_g
var_i = var_e / var_h
print(int(var_i))
