How many integers with distinct digits are there between 1000 and 9999 such that the absolute value of the difference between the first and the last digit is 4?
Just feeling my way through this one, ploddingly . . .
-- The first and last digits can be
- 4-0
- 5-1, 1-5
- 6-2, 2-6
- 7-3, 3-7
- 8-4, 4-8
- 9-5, 5-9
That's 11 possible pairs ... an odd number because the first digit can't be zero.
-- For each possibility, the middle 2 digits can be anything from 00 to 99 ... 100 pairs.
-- So the total list of numbers that satisfy the conditions comprises 1,100 of them.
I don't have a lot of confidence in this derivation, because I'm not completely
sure of what you mean by 'distinct digits', so I ignored that specification.

Find the absolute value of the difference of 2 consecutive even integers?
Let the two consecutive even integers be represented as ( n ) and ( n + 2 ). The difference between them is ( (n + 2) - n = 2 ). The absolute value of this difference is ( |2| ), which is simply 2. Therefore, the absolute value of the difference of two consecutive even integers is always 2.
What are the rules in adding integers with unlike signs?
For each pair of such integers, find the difference between the absolute values of the two integers and allocate the sign of the bigger number to it.
What is the connection between absolute value and integers?
None. Integers can be negative, absolute values cannot. Absiolute values can be rational or irrational fractions, integers cannot.

When two integers of opposite signs are added the result is the difference between the absolute values with the sign of the integer with the larger absolute value?
Yes.
How can you find the distance between two integers using the difference?
To find the distance between two integers using the difference, you simply subtract the smaller integer from the larger integer. The result will be the distance between the two integers on the number line. For example, if you have integers 7 and 3, you would subtract 3 from 7 to get a distance of 4. This method works because the difference between two integers gives you the number of units separating them on the number line.
What is the connection between absolute value and integers?
None. Integers can be negative, absolute values cannot. Absiolute values can be rational or irrational fractions, integers cannot.
How do you adding 2 integers with different sign?
Find the difference between the two numbers and attach the sign that belongs to the number with the bigger absolute value.

How do you determine difference when subtracting two integers with the same sign?
subract the number from the number, simple, at least that is what i found
How do you find the difference of two integers?
To find the difference between two integers, subtract the smaller integer from the larger one. You can express this mathematically as ( \text{Difference} = a - b ), where ( a ) is the larger integer and ( b ) is the smaller integer. If you don't know which is larger, simply subtract one from the other, and the absolute value of the result will give you the difference.
How can two integers with different signs be added?
When adding two integers with different signs, you can think of it as finding the difference between their absolute values. Subtract the smaller absolute value from the larger one, and the result takes the sign of the integer with the larger absolute value. For example, adding -3 and 5 involves calculating 5 - 3, resulting in 2, which takes the positive sign since 5 has a larger absolute value.
