TI 84-Plus Graphics Calculator

Bought a brand new graphics calculator today. It costs me over S$180. Yes, please don't doubt the price. It's that expensive! I had no choice but to buy it as my college student requires this for her cirriculum.

Sudents at college now do not need to sketch any graphs! Graphics calculator will do the job.

In future, kids do not need to write... they just use the keyboard and type. Lol

I'm still trying to figure out how to use this GC. If you do know, please HELP me!
