Is there a way to highlight and quickly evaluate a simple math expression without using elisp notation? For example, we can already evaluate the elisp expression `(+ 1 1)` in the following text snippet by putting point behind it and pressing `C-x C-e`.

```
Here is a math equation: (+ 1 1)

```

But can we also do

```
Here is a math equation: 1 + 1

```

And get its result?
