Absolute value does NOT just remove a negative sign.

late comment but these aren't brackets, they're absolute values. The absolute value of something is basically always positive, i.e. the absolute value of \-7 is 7 and the absolute value of 7 is 7. So the equation becomes 1- |-7| = 1-7 = -6. Edit: the \-7 has a blackslash so that youtube doesn't think that i'm trying to strikethrough the text
Absolute value means distance from origin, no matter the dimension. In one dimensions so numbers, it means distance from 0 on a number line. This means |+1| is 1 since the distance is 1 from 0.
Absolute value is a just a measurement of the distance from zero. So -6 is 6 away from zero. 1 is 1 away from zero, so it remains the same when you take the absolute value of it.

From where do you find such questions???

It is such a starting question, (too easy)
Lol we call it modulus here
If the minus and minus cuts then it is coming plus, so in my opinion the answer is 8, isn't it?
Me too thinking the same
No cuz you do absolute value first which changes sign to positive and then it becomes -6(which becomes 6)
A B and D are all positives
Meaning the final answer must be positive
B and C contain a "6"
A/D are random numbers (irrelevant)
We need a 6 that is positive... B didn't even look at the question
(If ur bad at math be good at guessing)
The correct answer is 8
You forgot to convert the minus sign into a + because - - is +
No it isn’t because you have to do the absolute value first so it’s - + is -
The absolute value of -7 is 7
Right answer is 8, you must convert absolute value of - sign to a + sign b4 u solve the value!
You do the the stuff inside it before you make it absolute value
I like your skill
Cool
Next level will be to select the graph of the equation from given options
i love your videos
The only way to get this wrong is to not know what absolute value means.
