Matrix multipliction $ZY" is undefined."$

Here.

$Z=[(-1,3),(0,-2)]=>color(red)("a matrix Z has 2 rows and 2 columns ."$

$Y=[(0,-3)]=>color(blue)("a matrix Y has 1 rows and 2 columns ."$

Hence,

$color(red)("Number of columns in Z"$ $!=$ $color(blue)("Number of rows inY "$

So, matrix multipliction $ZY "is undefined."$
