can we use unless with negative
Unless and If. Often when we are talking about present situations, we use unless instead of if...not. Unless means except if or simply it means if...not. Both of these examples have the same meaning and refer to the present time. You can't go on vacation unless you save some money.. If you don't save some money, you can't go on vacation.. You will feel cold if you don't wear a coat.. You will feel cold unless you wear a coat.. Unless is good to use when it highlights an exception to what is generally true.
