Math Is Fun Forum

Hello!

There is one question in my homework that I get a bit confused by. The question is:

"How is an index (indices) different from an exponent?"

I thought that they were the same thing.

Also while I'm on it, Is there anyone who can help me with this question since I don't quite understand it:

"Explain the possible use of symbolism by choosing to use a superscript postfix operand, the exponent, to denote an operator"

I really appriciate any help some anybody!
