A sigma notation but with multiplication instead of addition?

7.9k Views Asked by At

I am not a mathematician, so I apologize if this question will sound stupid. I am wondering is there some sort of notation which will resemble the one of sigma notation, but with multiplication instead of addition?

For example, the following expression: $2^1+2^2+2^3+2^4+2^5$ could be written as: $\sum_{i = 1} ^ 5 2^i$

But what about the following expression: $2^1*2^2*2^3*2^4*2^5$ ?

Is there some notation like sum sigma that could enable me to write this last expression a bit shorter?

Thank you very much.

You can use Pi notation (The $\LaTeX$ for this being \prod)

For example:

$$\prod\limits_{i = 1}^5 2^i = 2^1 \cdot 2^2 \cdot 2^3 \cdot 2^4 \cdot 2^5$$
