ACT Math Calculator Hacks-Part 2

This is the 2nd video which demonstrates a number of important operations that you should be familiar with and know how to do in order to perform well on the Math section of the ACT (for Part 1-go here https://youtu.be/YcwefgJkDBw). Similar to Part 1, these operations can help save you time, reduce errors, and answer more questions correctly on your practice tests and most importantly, your official test. Even if you do not have a TI-84 Plus model graphing calculator and have a different model, you can still benefit from knowing how to do these operations on your calculator; you will just have to lookup how to perform them on your specific model. The operations covered in this video are listed below with the timestamps and the worksheet reference guide can be downloaded here: https://view.publitas.com/p222-12941/ti-84-plus-calculator-functions/
