我怎样才能让这个三角形出现在句子旁边？

Question

当我将它放入 LateX 中时，它会在每个句子的前面出现缩进，我只希望句子像平常一样，然后在它旁边出现三角形。

\begin{gather*}
(0,0,0,1,0) \iff  
\qquad \qquad \qquad \qquad \qquad \qquad \qquad 4 \\
(0,0,0,1,0) + (0,1,0,-1,1) = (0,1,0,0,1) \iff  2 \qquad 5 \\
(0,1,0,0,1) + (1,-1,0,1,0) = (1,0,0,1,1) \iff  1 \qquad 4 \qquad 5 \\ 
(1,0,0,1,1) + (0,0,1,0,0) = (1,0,1,1,1) \iff         1\qquad 3 \qquad 4 \qquad 5 \\ 
(1,0,1,1,1) + (0,1,0,0,0) = (1,1,1,1,1) \iff  1\qquad 2\qquad 3\qquad 4\qquad 5 \\
\end{gather*}

Answer 1

像这样：

\documentclass{article}
\begin{document}
\[
\begin{array}{lc}
(0,0,0,1,0)                               \iff & 4                                 \\
(0,0,0,1,0) + (0, 1,0,-1,1) = (0,1,0,0,1) \iff & 2\qquad 5                         \\
(0,1,0,0,1) + (1,-1,0, 1,0) = (1,0,0,1,1) \iff & 1\qquad 4\qquad 5                 \\
(1,0,0,1,1) + (0, 0,1, 0,0) = (1,0,1,1,1) \iff & 1\qquad 3\qquad 4\qquad 5         \\
(1,0,1,1,1) + (0, 1,0, 0,0) = (1,1,1,1,1) \iff & 1\qquad 2\qquad 3\qquad 4\qquad 5 \\
\end{array}    
\]
\end{document}
