# How to add Boolean Operation "belong to", parallel and perpendicular?

Math123 shared this question 9 months ago

I can not find Boolean operation "belong to" , "Parallel", "Perpendicular" ,"Subset" , "Strict Subset" , "Union" , "Intersection" as keyboard shortcut, GGB keyboard etc..

Copy paste symbol for these operation work. Pls suggest.

l1 = {1,2,3,4,5}

1 (belong to) l1

also for lines parallel and perpendicular.

cierra la barra de entrada en el menu vista para que te aparezca el teclado, clic en ABC y luego en la tecla de simbolos abajo a la izquierda. Esto en la version 6 y supongo que en todas las que tengan teclado

PD: ¿se podria poner una ventana emergente de simbolos a la version 6 en la barra de entrada de forma similar a la de la version 5?

Hello @Simona Riva,

I have already seen this command. I need "belong to" a belong to list, "Intersection" of two lists, "Subset"etc..

Have you tried the conventional symbols for those?

Hello Michael,

I used these symbol by copy paste from google.

My question what is the way or keyboard shortcut to get these symbols. I can not find way to write these symbols (latex \in for belong to did not work). How can i write these symbols.
