Inlining calculations in a notebook

Question

Context

In $\LaTeX$, I can write something like:

  Thus, we have $x = \sqrt{2}$, ...

the $ ... $, as opposed to $$ ... $$, inline the LaTeX symbols.

Now, with Mathematica, I type a line of Input, I press ShiftEnter, and it produces the answer on a different line of output. However, I would like to type something like this:

  Thus, we get $c^2 - c = 1$, and solving it, we get $N[solve[c^2 - c = 1, c]]$, ...

The idea is that mathematica evaluates the command, takes the output, and inlines it into the sentence, rather than have it as a separate line.

I have no idea how to do this. From what I've read, this sounds like "cells", but from goofing around, it's not clear how to make this work.

Question:

How do I inline a mathematica expression, such that its output is displayed inline?

Answer 1

Does the Evaluate in Place command, found in the Evaluation menu, do what you want or most of what you want? Starting with your example, correcting a couple of typos

Thus, we get $c^2 - c == 1$, and solving it, we get $N[Solve[c^2 - c == 1, c]]$, ...

select the portion

  N[Solve[c^2 - c == 1, c]]

with the mouse and either use the menu command Evaluate in Place or type Shift+Ctrl+Enter to get

Thus, we get $c^2 - c ==  1$, and solving it, we get $ {{c -> -0.6180339887498949`}, {c -> 
    1.618033988749895`}} $, ...

inline.
