SV #5 Unit J concept 3

you need to keep in mind that these can have big numbers so don't freak out if you think you are doing it wrong. you also need to remember that for the 2nd row you can only use the 1st row. also when you go back for the second zero on the 3rd row you can only use the 2nd row to cancel out to get zeros.
