[Dusch4593]

Reason/inspiration (optional)

Under java/concepts/math-methods/terms/, create new term entries for the following methods:

• Math.log()

• Math.log10()

• Math.log1p()

• In the terms/ folder, make a new folder for each method (i.e., log, log10, and log1p).

• Inside the log, log10, and log1p folders, create a new markdown files called log.md, log10.md, and log1p.md, respectively.

• Inside the file, be sure to include a "Syntax" section with a ```pseudo code snippet.

• Also make sure to include an "Example" section with a ```java code snippet.

Please refer to the entry templates, content standards, and markdown style guide when working on the PR for this issue.
