In IRB, or saved as a program from Scite, put in something like:
response is always " Uninitialized constant MATH(NameError)
How can I tell if I have the MATH module in my installation? If I don’t
have it, how do I fix that? Thanks in advance.

You could do something like this.
Object.constants.grep(/math/i) # => [:Math]

Doh! Thanks. Can’t believe I did that.
