    will you please elaborate what these "toggle" words that keep popping out on every first word of each step?

    toggle means, if the previous state of a variable is T, change it to F

    32 rows, 64 rows... that gets pretty long... but sometimes we have to do it painfully..

    I would start a truth table with 4 variables this way: (We will need 2^4=16 rows) TTTT FFFF TTTF FFFT TTFF FFTT TTFT FFTF TFTT FTFF TFTF FTFT TFFF FTTT TFFT FTTF I wrote it like this to show for my last 8 rows I just replaced my T's with F's and my F's with T's that I had in the 1st 8 rows. I said okay also I'm gonna start with 8 T's and 8 F's pattern Then second column I did 8/2 T's and 8/2 F's pattern Third colmn I did 4/2 T's and 4/2 F's pattern And fourth column I did 2/2 T's and 2/2 F's pattern Does that make sense?

    if you're showing first rows as TTTTT, you must show last row as FFFFF

    u can work out using any directions, but the general way we represent truth tables is common everywhere
