Chapter 1 Videos and Notes

Note: we go out of order, as you will see reflected in the schedule. I have put the videos in order of the schedule below.

Section 1.5

Note: This section is a review of adding and subtracting with whole numbers and decimals (not fractions). If you feel you need a review on how to do this without a calculator, you can watch the following videos, which do not have notes but can be a good way to refresh your memory. You will get a ton of practice in ALEKS on this, so do not fear if you are rusty!

Section 1.6

Note: This section is a review of multiplying and dividing with whole numbers and decimals (not fractions). If you feel you need a review on how to do this without a calculator, you can watch the following videos, which do not have notes but can be a good way to refresh your memory. You will get a ton of practice in ALEKS on this, so do not fear if you are rusty!

Section 1.4

Note: this is a review of types of numbers and the number line. If you need a review of this, I have included a few videos below but otherwise ALEKS will help get your caught up on this!
