Hello. My name is Adriane, and I would like to help you with your Algebra. Today's topic is going to be on *Absolute Value*. I am going to give you directions, so please follow along. If you get lost please feel free to message me. Get those pens ready and here we go!
DIRECTIONS:
The first thing you will need to do is pull out a piece of notebook paper and on on the third line down draw a number line, and number. Zero goes in the middle of course. On the right hand side please right 1, 2, 3, 4, 5, and on the left hand side write -1, -2, -3, -4, and -5.
The absolute value of x, denoted "| x |" (and which is read as "the absolute value of x"), is the distance of x from zero. This is why absolute value is never negative; absolute value only asks "how far?", not "in which direction?". This means not only that | 3 | = 3, because 3 is three units to the right of zero, but also that | –3 | = 3, because –3 is three units to the left of zero.
NOTE: The absolute value notation is not brackets or parenthesis. They are strictly bars
It is important to note that the absolute value bars do NOT work in the same way as do parentheses. Whereas –(–3) = +3, this is NOT how it works for absolute value:
* Simplify –| –3 |.
Given –| –3 |, I first handle the absolute value part, taking the positive and converting the absolute value bars to parentheses:
–| –3 | = –(+3)
Now I can take the negative through the parentheses:
–| –3 | = –(3) = –3
As this illustrates, if you take the negative of an absolute value, you will get a negative number for your answer.
You have all done a great job today. If you still have questions or this didn't help you much please feel free to message me, and I will get back to you A.S.A.P
