can I just get Scala REPL without creating a project using sbt

Question

I want to install Scala REPL on windows10. I looked around on internet but I can't seem to find how I can just get scala binaries and REPL. The links seem to suggest that I either use Intellij or sbt. If I get sbt, the way to create a project is eg sbt new hello which seem to be doing a lot of stuff (see below)!

Question 1 - How can I get just REPL. I don't want to create projects, I just need a command line tool to practice writing expressions.

Question 2- After installing sbt, I did sbt new hello and I was overwhelmed to see the result in the command line. What is sbt doing below and why the project still wasn't created (see the error in the end, Template not found for: hello? I have truncated the output to stay within the word limit

C:\Users\manuc\Documents\manu>mkdir scala_programs

C:\Users\manuc\Documents\manu>cd scala_programs

C:\Users\manuc\Documents\manu\scala_programs>sbt new hello
