Math:公式布局
出自OOo 中文手册翻译
本节针对OOoMath中比较难处理的复杂公式给出一些建议。 The most difficult part of using OOoMath comes when writing complicated equations. This section provides some advice about writing complex formulas.
[编辑] 善用括号 Brackets are your friends
OOoMath并不知道运算符号的顺序，您必须使用括号来明确告诉它。参考下面的示例： OOoMath knows nothing about order of operation. You must use brackets to state order of operations explicitly. Consider the following example:
| 标记语句 | 结果 |
|---|---|
| 2 over x + 1 | <math>{2 \over x} + 1</math> |
| 2 over {x + 1} | <math>2 \over {x + 1}</math> |
[编辑] 多行公式
假定您需要输入包含多行的公式，如下图的例子： Suppose you want to type an equation covering more than one line. For example:
x=3
y=1
<math>x = 3\,\!</math>
<math>y = 1\,\!</math>
您的直接反应应该是直接输入 回车 键。但是这样只能在编辑器中产生一个空行，但公式却不会分行。您必须使用newline命令。如下图： Your first reaction would be to simply press the Enter key. However, if you press the Enter key, though the markup goes to a new line, the resulting equation does not. You must type the newline command explicitly. This is illustrated in the table below.
| 标记语句 | 结果 |
|---|---|
| x = 3 y = 1 | x = 3 y = 1 <math>x = 3 \ y = 1</math> |
| x = 3 newline y = 1 | x = 3 y = 1 <math>x = 3\,\!</math> <math>y = 1\,\!</math> |
