 </html> Some complete sentences can be written purely in mathematical symbols, such as equations (e.g., $a^3=b^{-1}$), inequalities (e.g., $x<5$), and other relations (like $5\big|10$ or $7\in\mathbb{Z}$). These statements usually express a relationship between two mathematical \emph{objects}, like numbers or sets.  However, it is considered bad style to begin a sentence with symbols.  A common phrase to use to avoid starting a sentence with mathematical symbols is "We see that..." </html> Some complete sentences can be written purely in mathematical symbols, such as equations (e.g., $a^3=b^{-1}$), inequalities (e.g., $x<5$), and other relations (like $5\big|10$ or $7\in\mathbb{Z}$).

   - **Show the logical connections among your sentences.** Use phrases like "Therefore" or "because" or "if$\ldots$, then$\ldots$" or "if and only if" to connect your sentences.   - **Show the logical connections among your sentences.** Use phrases like "Therefore" or "because" or "if$\ldots$, then$\ldots$" or "if and only if" to connect your sentences.
-  - **Use paragraphs to organize your work into logical chunks. If every sentence starts a new paragraph, then you are not logical organizing your work.  Similarly, if you have a long proof and all your sentences are in a single paragraph, you are not logically organizing your work. Use paragraphs to put structure and order to your work. +  - **Use paragraphs to organize your work into logical chunks.** If every sentence starts a new paragraph, then you are not logical organizing your work.  Similarly, if you have a long proof and all your sentences are in a single paragraph, you are not logically organizing your work.
