+**LoveIt** theme supports `raw` shortcode to avoid these escape characters,
+which helps you write raw mathematical formula content.

+Example `raw` input:
+
+```markdown
+Inline Formula: {{</* raw */>}}\(\mathbf{E}=\sum_{i} \mathbf{E}_{i}=\mathbf{E}_{1}+\mathbf{E}_{2}+\mathbf{E}_{3}+\cdots\){{</* /raw */>}}

+Block Formula:

+{{</* raw */>}}
+\[ a=b+c \\ d+e=f \]
+{{</* /raw */>}}
+```

+The rendered output looks like this:
+
+Inline Formula: {{< raw >}}\(\mathbf{E}=\sum_{i} \mathbf{E}_{i}=\mathbf{E}_{1}+\mathbf{E}_{2}+\mathbf{E}_{3}+\cdots\){{< /raw >}}
