A cool way of multiplying by 11

When @howie_hua has you doing math after work when your entire job is doing math at work 😂

@MsFox_Sil I’m going to show the math group this week!

I knew this trick (learned it with 2 digit numbers x 11) but never thought of the reasoning. Thanks!

@MCampbellEdu You could show your 8s this trick and then have them figure out why it works!

@MrLewisVB a good warm up!

@MrshinrichsT Can't remember the grade you are teaching, so not sure if this would help your students.

As much as I loved this method, I have to applaud the reference of the T-shirt 💊
