Calculate the value of
|7.3| – |–2.1|
i think its 5.2
Thanks that is what I thought because you take the numbers and subtract them without the absolute value signs. Thanks!
Excellent, that's exactly what I would do:
|7.3| – |–2.1|
=7.3-2.1
=5.2
To calculate the value of |7.3| - |–2.1|, we need to understand what the absolute value represents and then perform the subtraction.
The absolute value of a number is its distance from zero on the number line and is always positive. So when you see |x|, it means that the number x, regardless of its sign, is positive or zero.
In this case, |7.3| means that the absolute value of 7.3 is 7.3 itself since it is already a positive number.
For |–2.1|, we need to negate -2.1 to get a positive value. Negating a negative number makes it positive, so |-2.1| becomes 2.1.
Now, we can calculate the expression |7.3| - |–2.1|:
|7.3| - |–2.1| = 7.3 - 2.1
Solving this subtraction, we have:
|7.3| - |–2.1| = 5.2
Therefore, the value of the expression |7.3| - |–2.1| is 5.2.
