### Find the entry in the second row, first column of AB

Please let me know if I did this correctly.

I have Let A = [1 4] and B = [3 -2]. find the entry in the second row, first column of AB.
2 3                4  6

I multiplied A and B to get AB and the number I got for the second row, first column of AB was 18. Did I do this correctly?
