Explore high school equivalency options—GED, HiSET, and TASC—and learn costs, delivery methods, and unit-based math lessons with videos, quizzes, and worksheets to pass any HSE exam.
Unit 3 presents five lessons on negative numbers, using the number line to subtract positives and negatives, solve word problems, and multiply or divide negatives to understand negative components.
Use the number line to add and subtract by starting at a number and moving right for positives and left for negatives; compare absolute values to determine the sign.
Subtracting on the number line starts at the initial value and moves left for the subtraction, illustrating positive and negative results as the line extends infinitely in both directions.
Explore how subtracting negative numbers works using a number line, where two negatives cancel and subtraction becomes adding a positive.
Explore negative numbers through word problems in money, temperature, and elevation. Learn to combine positives and negatives, compute balances, overdraft fees, and temperature differences.
Learn the rules for multiplying and dividing negative numbers, applying same-sign results as positive and opposite-sign results as negative, with worked examples.
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.
