How many distinct positive digit integers can be formed using the digits 1 to 4 each once such that no adjacent digits differ by more then two?
Well, let's see.
The number of distinct ways to order the digits 1 to 4 is 4x3x2(x1) = 24. That's not too many to list, so let's do so:
1234
1243
1324
1342
1423
1432
2134
2143
2314
2341
2413
2431
3124
3142
3214
3241
3412
3421
4123
4132
4213
4231
4312
4321
The ones where 1 and 4 are next to each other are forbidden by your adjacent numbers rule. That's 2 of the numbers starting with 1 or 4 (4 total), and 4 of the numbers starting with 2 or 3 (8 total). In all, only 12 of the 24 possible numbers are allowed by the adjacent rule.

How do signed numbers differ from integers?
Positive signed numbers with have a + Positive integers will not.
What happens when we add subtract multiply and divide integers?
When we add or subtract integers, the result depends on their signs: adding two positive numbers or two negative numbers yields a positive or negative result, respectively, while adding a positive and a negative number involves finding the difference between their absolute values and taking the sign of the larger absolute value. Multiplying integers results in a positive product when both integers have the same sign and a negative product when they have different signs. Dividing integers follows the same sign rules as multiplication; the quotient is positive if both integers share the same sign and negative if their signs differ. Overall, operations involving integers adhere to specific rules regarding their signs and absolute values.

What is rule of subtraction integers?
if substracting by two negatives your going to add ex: -2-(-5) it would be positive 7. if your substracting with two differ numbers it you would substract and take the sign the sign of the biggest number.ex: 2+(-3) it would be-1 sice 3 is bigger than2 you take the sign of 3
