Lesson 7: Comparing absolute values

# Comparing absolute values on the number line

In this math lesson, we explore absolute values and inequalities using a number line with three numbers: a, b, and c. We determine the truth of four inequalities: a < b, |a| > |b|, |a| < |c|, and a < c. By understanding number positions and absolute values, we can easily solve these inequalities.

• Did Sal actually say " the number "b"?
• Yes, he even said that to A and C.
• what happens if you get an negitive of an negitive
• the negative of a negative number would be the opposite of a negative number, a positive number.

example: -(-4) = 4.
• Did Sal really say number A number B number C?
• Yep, it's because variables are letters that replace numbers so you could refer to them that way, which Sal did.
• In the last review of Lesson 6 it had a question where it compares |9|___ -9 and the answer was not equal but rather
|9|>-9, so why here |a| = |c|?
• I Watched it it it still says not finished
• You have to watch a certain amount of the video to complete it. If you skip the video enough then it wont finish, just watch it again some more

• The letters are variables to fill in unknown numbers, so probably that's why.
