The answer is not very long. I am sure we might have reached a problem where we decided we are done with Mathematics as soon as this exam is over but in real life it isn’t t the case. You need Math to do literally everything after all why do you think it is called the language of the universe.
From the moment you look at the watch and observed the time numerous calculations have already passed through your mind. When you go shopping you calculate the amount in your hand and how affordable it would be to buy that certain something. Similarly you can pick any scenario in your daily life where even the tiniest application of math is necessary to perform the said task. So if you are trying to calculate how long you can go without using math or any of its concepts, I am afraid you are already using it.
