My mother is 43 years old this year. A few years ago, her age was five times her daughter's age, who is 11 years old this year. Find how many years ago it was.
5 11 [OP_MUL] 43 [OP_SUB] 5 1 [OP_SUB] [OP_DIV]
var_a = 5
var_b = 11
var_c = var_a * var_b
var_d = 43
var_e = var_c - var_d
var_f = 5
var_g = 1
var_h = var_f - var_g
var_i = var_e / var_h
print(int(var_i))
