When you add 12 to a number and divide it by 4, the quotient is 12 and the remainder is 3. Add 12 to that number in question and multiply it by 4 to find the value.
12 4 [OP_MUL] 3 [OP_ADD] 12 [OP_SUB] 12 [OP_ADD] 4 [OP_MUL]
var_a = 12
var_b = 4
var_c = var_a * var_b
var_d = 3
var_e = var_c + var_d
var_f = 12
var_g = var_e - var_f
var_h = 12
var_i = var_g + var_h
var_j = 4
var_k = var_i * var_j
print(int(var_k))
