For puzzles about forming numbers using other numbers and mathematical operations. Use with [mathematics]
This tag is for puzzles of the following form:
Use the numbers $a_1,a_2,\dots,a_n$ and the operations $o_1,o_2,\dots,o_m$ (for example $+,\times,!$) to form the target number $N$.
Other restrictions may be added. For instance, it may be specified that each of $a_1,a_2,\dots,a_n$ may be used exactly once, or only in a certain order.
