Simplify - 1-3[4^2-3 (-6) ]

We are given - 1-3[4^2-3 (-6) ]

First step is to calculate potentions:

-1-3[16-3 (-6) ]

Now if we have to calculate something inside brackets we do if not we do multiplication / division:

-1-3[16+38]

Now we repeat previous step:

-1-3[54]

Now we multiply:

-1-162

Now we substract:

-163
