SAT Math Calculator Hacks-Part 1

This video demonstrates a number of important operations that you should be familiar with and know how to do in order to perform well on the Calculator section of the SAT. These operations can help you solve problems almost entirely on the graphing calculator and thus, help save you time, reduce errors, and answer more questions correctly on your practice tests and most importantly, your official test. This video (part 1) will feature 7 problems while part 2 (which will be posted here as soon as it is published) will have 7 additional problems. 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/. The ACT Math videos which explain the calculator operations in a step-by-step process with greater detail can be seen here:
