This is the Third Unit in a series of courses on High School Equivalency Math Prep. The HSE can be obtained by taking the GED, TASC, or HiSET tests depending on the state you live in. All information pertaining to the GED, TASC, HiSET, HSE can be found in the introductory video.
In this course specifically, we will be discussing Negative Numbers. You will use the number line to identify the differences between adding positive numbers, adding negative numbers, subtracting positive numbers, and subtracting negative numbers. You will then take this information and apply it to Word Problems. Finally, you will learn the rules for multiplying and dividing negative numbers.
By the end of the unit, you should feel comfortable with negative number operations - with and without a number line.
