### How the \alignat works in ams package

I've always found the description of alignat based on the number of & tokens confusing. It's simpler than that: first you decide how many parts your alignment consists of, then adjust the number ...

### How to align operators using alignat or someother environment?

You have to understand that, in the align and alignat environments, for n alignment points, one needs 2n – 1ampersands: the first one is to introduce a ne column (from the second column), the next one ...

### How to properly align two numbered equations?

You can use IEEEeqnarray from IEEEtrantools. Here I specify alternating centered columns, one for ordinary material and one for relation/operation symbols. I also add a simpler syntax for the ...

### Writing a system of Linear Equations

The \begin{alignat*}{4}[left = \empheqlbrace] solution which you employ in your own answer requires hand-editing "& 6" to "& 6\phantom{0}" in order to generate the appearance of left-alignment ...

### How to align single-digit numbers with multi-digit numbers in multi-line equations?

Use array features. Setting the intercolumn spacing to zero and forcing TeX's automatic spacing around binary relations or operations is simple. In the second example, which I like better, I also ...

### Numbering for a whole system of equations

You can use alignedat inside equation. I added a couple of adjustments for having the vertical dots centered with respect to the equals signs and not so far away from the last line. \documentclass{...

### How do you do a "staircase align" in Latex?

You can use alignat, but it's handier if we don't have to compute the number of necessary &'s and let TeX do it. The main left-hand side is given as argument to the environment, the rest is in the ...

### How to properly align two numbered equations?

In your case you could use the eqparbox package for example. It helps to make pairs of boxes of the same width. After making them, it is sufficient to use simple align' for your equations to be ...

### Error message when using split within alignat

To have just one equation number it is reasonable to use equation as the outer environment. A split will provide a single alignment point, if you need more use alignedat, or aligned, instead. For ...

### \phantom not giving correct space?

You forgot to put {}< at the beginning of the \phantom. \documentclass{article} \usepackage{amsmath} \begin{document} \begin{alignat*}{2} d\bigl(x^{(j)}_j, x^{(i)}_i\bigr) & \le d\bigl(x^{(...

### How to align operators using alignat or someother environment?

You can use the new package autoaligne, augmented with a trick for removing the + sign from the first term in the second line. The \f macro is just for slimming the input. It would be better if the ...

### How to align operators using alignat or someother environment?

You may find the following solution, which uses only the array package, instructive. The array environment used in the solution has 23 [!] separate columns: 12 for the very first term and the ...

### When to use which alignment environment?

amsmath is derived from AMSTeX (amstex.tex) which does not have * forms but otherwise has mostly similar naming, including the x- variants. The environments that start math displays are documented in ...

### Equation alignment with varying number of columns

I suggest you use a \mathrlap directive (provided by the mathtools package, a superset of the amsmath package) to "hide" the t_i + t_j + t_k + t_m part from the remaining equations; see the ...

### How the \alignat works in ams package

alignat can also align a single equation, if needed. That is, \begin{alignat}{1} f(x) &= a x^2 + b x + c \end{alignat} would yield the same output as \begin{align} f(x) &= a x^2 + b x + ...
