I think I can address your question for you without any problems. At the core of the mathematical problem, what is essentially being asked is, "what is the DIFFERENCE between the number three (3) and the number four (4) on the real number line?". The the following is an example of a short segment of the real number line (the parentheses are only used by me to help with the spacing limitations of the answers posted on Mybestanswer so you may ignore them.):

.(-2)(-1) (0) (1) (2) (3) (4) .

So the distance between the number three (3) and four (3) is merely a subtraction problem. The order with which they are arranged in the question is irrelevant since the distance between 3 and 4 is the same measured distance as that which is between 4 and 3. In other words, the distance is completely unrelated to which is used as a starting point and which is used as the end point (i.e. The distance from 'here' to 'there' is the same as the distance from 'there' to 'here'!).

So to make sure your distance is always a 'positive' number, representative of a distance, we take the answer's absolute value. This is written for any value x as: |x|. In this case the 'x' is simply replaced with the subtraction problem like this |3-4|.

This tells us that we could have just as easily have measured the distance the other way and received the same answer, like this |4-3|. The meaning is the same, and therefore the answer is the same as well.

To answer your question you would calculate the inside of the absolute value bars first (3 - 4 = -1), leaving you with, |-1|, or the 'absolute value' of negative one. All this requires you to do is remove any negative for the inside value (if there is one present), thus, |-1| = 1, which is the final answer, one (1). This answer (one) is also referred to as the unit or unity. The unit (1) is the special value that allows multiplication by any nonzero real number to produce itself: (e.g. 5 x 1 = 5; 173 x 1 = 173; -77 x 1 = -77), according to the 'identity axiom' which defines the real number line (formally named the complete ordered field.)

If, the question were rearranged because you had decided to measure the numbers (three and four) in the opposite ORDER, the question would instead appear like this: |4-3|, and would have identical meaning, thus an identical answer: |4-3| = |1| = 1. So what is being said is that regardless of the order you use to measure distance, you will always receive a positive value.

To be clear, the final answer to your question is one (1). Because, |3-4| = |-1| = 1.

This question is asking for the absolute value of 3-4. To find absolute value (which means how far an integer is from 0) you drop the I I around the number and also drop the sign. For example, the absolute value of -4 would be written I -4 I and be equal to 4.

Here it would take two steps to find the answer.

1) Find the answer to 3 - 4 inside the I I : 3 - 4 = -1

2) Find the absolute value of that answer: l -1 I = 1

The answer then is 1 .

The pipe symbol "|" refers to absolute value. Absolute value is the distance from zero, even if you're going in the negative direction.

So first you would solve the problem, 3-4, which would give you -1. That value is 1 away from zero.

The answer is 1 (or technically: +1)

The two linear bars is the sign for absolute value. The way absolute value works is you perform the equation normally, then whatever answer you get you make it positive. Hence if you get a positive leave it alone. If you get a negative make it a positive of the same number value. So |3-4| = 1

...What does the | stand for if anything? If nothing the answer would be negative 1, -1

My math skills go back to when we use to count with fingers.

The answer is +1 which is the same as 1 because absolute values can only be positive. That's a very simple was of putting it.
