I am new to latex and am trying to create the following in latex: [![enter image description here][1]][1]

It looks similar to what I want when I use this:

$\scriptsize 0_{{\big T}{\small 1}} =

However, I get the following error message:

! Missing delimiter (. inserted). T l.10 $\scriptsize 0_{{\big T }{\small 1}} = I was expecting to see something like (' or {' or \}' here. If you typed, e.g., {' instead of \{', you should probably delete the {' by typing 1' now, so that braces don't get unbalanced. Otherwise just proceed. Acceptable delimiters are characters whose \delcode is nonnegative, or you can use \delimiter '.

I am not sure how to fix the error and am hoping someone on here can help me :) [1]: https://i.sstatic.net/Ws7No.png
