==== definition ====

binary mekso operator: Let the inputs <span class="MATH"><i>X</i><sub>1</sub></span> and <span class="MATH"><i>X</i><sub>2</sub></span> be sets in the same universal set <span class="MATH"><i>O</i></span>; then the result of this operator applied to them is  MATH
 $X_{1}^{c}  \cap X_{2}^{c}$
 
<span class="MATH"><i>X</i><sub>1</sub><sup>c</sup>∩<i>X</i><sub>2</sub><sup>c</sup></span>, where for any  MATH
 $A \subseteq O, A^{c} = O \setminus A$
 
<span class="MATH"><i>A</i>⊆<i>O</i>, <i>A</i><sup>c</sup> = <i>O</i> <img alt="$\setminus$" src="/jbovlaste_export/5slAL8xWzc/img1.png" style="height: 2.38ex; vertical-align: -0.70ex; "/> <i>A</i></span>.

==== notes ====
This is a dual to [[xa'ei'o|xa'ei'o]] and largely has the same properties; only one of them is needed in any operator system.
