my teacher ask me What recommendation does the calculator make for you? what that mean
If you enter data into a calculator, and you enter it correctly, then the calculator gives you an answer, right? Do you always take the calculator's answer? Or do you also do some mental math or estimation to ensure for yourself that the calculator's answer is correct?
What if you entered the data incorrectly? You'd get an incorrect answer, right? But if you already have done some mental math or estimation, you should have a good idea of whether the calculator's answer was correct or not. If the "recommendation" (the calculator's answer) is not what you expected (what you estimated), then what would you do?
Are you using a speaking calculator? If so, those just say the math you put in the keys as a math sentence. If you have not completed the sentence, it gives you an incomplete sentence, as "two plus two "
