Guass jordan method

[Princess Valiant]

Wayyyyyy off topic but.....

So looooong time ago I was able to do the guass Jordan method of substition in seconds on the calculator on the right.

I went to show a college kid how to do it and it seems I forgot.

So I went and bought the updated version to that calculator, the one on the left which is the 2021 version.

Either one has a matrix function, anyone know how to whiz through the matrix process to get an x and y value on either one?

I know it's possible but I need a memory jog.

We are working on 3x3 matrix set ups.

I'm thinking these calculators should be able muscle through the simplex process too and kinda do row echlen form instantly.

Yea, I know how to do it the long way but I thought it was cool to be able to check it. Plus it shows how far these calculators have evolved

Three blocks up, take a right, up on the left about a half mile or so and you caint miss it.

You can’t miss it. Wish I had a dollar for every time I heard that line and missed it.

Can't the computer do it?

I mean it IS the most powerful mathematical tool ever invented.

The extent of my math abilities is sorting "order of operations" in excell spreadsheets, so they can do the work for me.

...and I design computer networks.
