Digging the poster of the TI-84 Plus Silver Edition. I personally use the older TI-83 Plus witch is a little slower but still really good. There was a house built down the street from where I live and it was built 5 feet closer to the curb then it was supposed to be making it so it broke some rule about houses having to be so far back from the sidewalk so you don't have houses that have the front door opening on the side walk or something, but anyway the whole thing was ripped down right after they started to put the plywood on the framing and they rebuilt the whole thing 5 feet back but guess who took the blame and got fired that's right the surveyor.
