It is hard for people to be silent because we are humans and have a mind. Our minds will not let us be silent, there is a voice constantly talking inside our head. If something would be bothering us, we could be quiet for a while, but there would be something eating us out for not saying anything. For instance, if somebody was getting bullied in front of me. I would not be able to stay quiet and mind my own business. I would have to stand up for the person being bullied and call for an adult to help. Another example would be me being told that i a female am unable to do ''man jobs,'' i have this strong voice inside of me that despises people who do not believe in equality among genders. I cannot stay quiet if i hear myself or anyone around me getting treated unequally. This shows that no matter who we are, we are humans and have feelings. If we see something that we do not think us fair, we will fight for what is right. People should never stay silent and always speak of what is on their mind.
It is not a full page essay but i thought you could use some of these points in writing your own essay.
Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
