Answer:
This is pretty ez.
Question 1.
If m becomes -m, that means its value will become switched around also, so the answer for that is 6.
Question 2.
5 - [-(-2)]
Those are brackets, basically parenthesis. But they don't matter here anyway.
So it becomes
5 - 2 = 3
The answer is 3.
Question 3.
|-4.3| + |4.3|
Absolute value basically just turns negative numbers into positive numbers.
So it becomes : 4.3 + 4.3 = 8.6
The answer is 8.6.
Question 4.
Same thing, absolute value just turns negative numbers into positive numbers.
It becomes : 1.4 + 2.3 which equals 3.7.
The answer is 3.7.
Question 5.
Whenever an equation is inside of absolute value marks, you do the equation first.
|23 - 4|
|19|
Then find the absolute value of the remaining number.
19.
The answer is 19.
Note: You should read your books, this is fairly easy and absolute value marks aren't something to sweat about.
