What are some patterns in the multiplication table?

What are some patterns in the multiplication table? Please list a few..I already have 4 or 5 but need to see if i’m missing anything.

Thank you!!

Tens always have a zero at the end.
Elevens initially repeat the number being multiplied by.

    9 x 3 = 27 | 2+7=9
    9 x 4 = 36 | 3+6=9
    9 x 5 = 45 | 4+5=9
    .. etc

    5 x anything ends in 0 or 5
    2 x anything ends in even #
