I added 2 files(4 lines) of comments.

And i'm only gonna git add one file.

git add calculator.py: designate as a target of commit

git status: show current status of project directory which git knows

git add License: designate as a target of commit

mkdir meeting-log: make new directory which is gonna save meeting logs

cd meeting-log

touch day1: make document named "day1"

touch day2: make document named "day2"

cd ../: go back to MathTool directory

git add meeting-log

if you add directory, all files in the directory are added to staging area.

How add to all files in once

1. modify 2 files
