There are many benefits to using folders when working with lots of files. Here are a few examples:
- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.
- You can use folders to group files together into a specific group. For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.
- As in the example above you can nest folders to create sub-categories. Documents might include folders for Homework, Stories, Poems
- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!
Answer:
1.) -2 - 1i
2.) -2 - 1i
3.) commutative
Explanation:
Given :
z = 1 + 3i
w = −3 − 4i
1.)
z + w :
1 + 3i + (-3 - 4i)
1 + 3i - 3 - 4i
1 - 3 + 3i - 4i
-2 - 1i
2.)
w + z
-3 - 4i + 1 + 3i
-3 + 1 - 4i + 3i
-2 - 1i
z + w = w + z
Hence, come number addition are commutative

Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.
