Sometimes a long equation needs to be broken over multiple lines, especially if using a double column export style. You typically have to enter an additional environment. When numbering is allowed, you can label each row individually. 1.23 is a number of the whole multiline equation (or a set of equations) and 2 is a number of a single line of the multiline equation (or of a single equation within a set) What happens when the post has been flagged for migration? You can suppress the number on any particular line by putting \notag before the \\; So your equation should look like this (some bits removed from your equation to make it shorter): \begin {align} z_1^2 &= \left ( . By default, LaTeX will number equations . Delete the old equation including its math-box placeholder. Sorted by: 40. Go to website. Could be fixed by letting KaTeX add some extra margin on top of the equation number, which would be possible since KaTeX knows the height of the current equation line. Multiline equations alignement: Method 2. Changing the number of columns. Meaning the next equation has no integer solutions: \ [ x^n + y^n = z^n \] \end{ document } Open this example in Overleaf. Code: \begin {equation} \begin {split} a &= b + 1\\ c &= a + 10 \end {split} \end {equation} Mar 17, 2010. Insert -> Label. This should be numbered (1) (1) x 2 d x. It is necessary to ensure that the = signs are aligned with one another. A similar result is obtained when using the align environment. Create a new equation of the same type. Using the multiline, aligned packages. Copy the old equation label. Now, I am writing monthly technical report. But equation* is not numbered. In large equations or derivations which span multiple lines, we can use the \begin {align} and \end {align} commands to correctly display the aligned mathematics. I have a very wide equation that I can't put on one line. As shown in the example above, utilize the split environment if you would like to split the equations into smaller parts.
