Questions
1.Why is it important to know about lists?
A: It is important to know about list because we use lists everyday in our life. By using list we can understand abstraction and DUDE we use abstraction everyday in our life. Also by understanding list we can apply the modulus division and get to know the how it functions. It also teach us about global users which is very essential to computer science.
2. What is modulus division?
A: Modulus division is similar to a division. However, you just show the remainder. For example if it is 18/5 and if you use modulus division it is NOT 3.6 but it is 3 remainder 3. So 18 mod 5 = 3. Just think that modulus division is the left over pizza you had with your friends. You have 8 pizzas and 5 of your friends ate it and you have 3 pizza left.
3.How is a list an example of abstraction?
A: List is an example of abstraction because we can just type things and BOOM it shows up. In the app uses modulus division and get all things complex ideas. However, by using abstraction, we made making list easy for the user. When the user clicks on the middle item, it just shows the middle item right away. The user do not have to see the process of the modulus division so they won't get a headache.
