Text Formatting ⇒ Error in code

[Rahul]

Code: Select all

\noindent
 ${b_{1_{new}}$ and $b_{k_{new}}\}$ in the equations 4.5 and 4.6 are integers.Their fractional part is ignored.Apply ${s_{i_{new}}$ and ${o_{i_{new}}}$ to \${{a_{k+1} ,a_{k+2} ,a_{k+3} ,...,a_{n}\}}$ producing \${b_{(k+1)_{new}},b_{(k+2)_{new}},b_{(k+3)_{new}},...,b_{n_{new}}\}$. Now,we write only \${b_{1_{new}},b_{(k+1)_{new}},b_{(k+2)_{new}},...,b_{n_{new}}\}$ over the corresponding pixels of $R_i$.

Required output is given in figure. Please check the code and tell the error.I hv tried many times.Ty in advance.

Be more careful in placing backslashes (\) and braces ({}).

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{mathtools}  % loads »amsmath«

\begin{document}
  \noindent
  $b_{1_\text{new}}$ and $b_{k_\text{new}}$ in the equations 4.5 and 4.6 are integers.
  Their fractional part is ignored. Apply $s_{i_\text{new}}$ and $o_{i_\text{new}}$ to
  $\{{a_{k+1} ,a_{k+2} ,a_{k+3} ,\ldots,a_{n}\}}$ producing
  $\{b_{(k+1)_\text{new}}, b_{(k+2)_\text{new}}, b_{(k+3)_\text{new}}, \ldots, b_{n_\text{new}}\}$.
  Now, we write only $\{b_{1_\text{new}}, b_{(k+1)_\text{new}}, b_{(k+2)_\text{new}},\ldots, b_{n_\text{new}}\}$
  over the corresponding pixels of $R_i$.
\end{document}
