absolute value.
absolute value
So, they don't really mean anything?
So |1/2-3/4| = 1/2-3/4
So |1/2-3/4| = 1/2-3/4
Yes, they do mean something. For example,
1/2 - 3/4 = -1/4
|1/2-3/4| = 1/4
1/2 - 3/4 = -1/4
|1/2-3/4| = 1/4
How come the answers are different? Please explain, whats its function in helping to solve the equation.
Thanks.
Thanks.
The secret word here was in the two posts by others (not mine). Look up the word "absolute value" and see what it means.
Here is a really good site that explains this and many other math problems.
