Avoiding transformations after typing formulae?

I often encounter undesirable transformation of formulae I type in Mathematica. For text and formulae I use cells with Text style.
Say, I try to enter the formula

But Mathematica automatically transforms it into

after finishing the typing.

Is it possible to cancel that transformation?

I’m not sure I understand. Can you give us the steps to reproduce a simple example of your problem?

Simply.
I start typing in the cell with Text style. I press the buttons:

0, =, x, Ctrl+Shift±, 1, RightArrow, <, x, Ctrl+Shift±, 2, RightArrow, <, ., ., ., <, x, Ctrl+Shift±, N, RightArrow, = , 1

When I type the text next to the formula, it (formula) sometimes triggers to the expression with Subscript[].

Mathematica 10.4, Windows 8.1

To my mind, inline formulae in Text cells should be typed in a specified mode, not just by typing letters, sub/superscript etc.

Something similar happens to me if I write, for example, Subscript[x, 1] (in 2-dimensional notation) in an input cell, then select the expression, and finally choose the menu Insert > Typesetting > Start inline cell. What I get literally looks like this:

\!\(
 \*SuperscriptBox[\(x\), \(2\)]\)

Likewise with Superscript. However, I think this is not a natural sequence of operations.
