Yuna and her grandmother are 12 and 72 years old, respectively. A few years later, grandmother's age is 5 times Yuna's age. How old is your grandmother at that year?
72 12 [OP_SUB] 5 [OP_MUL] 5 1 [OP_SUB] [OP_DIV]
var_a = 72
var_b = 12
var_c = var_a - var_b
var_d = 5
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))
