$u + 9 = - 10$
​

Answer 1

Answer:

follow me plsss

Explanation:

You should not use math, when it is normal text. Use \textsuperscript instead: 2\textsuperscript{nd}. You can also define a shortcut for this, e.g.

\newcommand{\ts}{\textsuperscript}

Then you could use 2\ts{nd} in the text.

Edit:

An even nicer solution is to load the package nth with the option super and use the \nth command:

\usepackage[super]{nth}

\nth{1}, \nth{2}, \nth{3}, \nth{4

Answer 2

Answer:

Hi!

u + 9 = -10

so,

u = -10 -9

therefore,

u = -19
