adding
1. like sign, add their absalute value & copy the common sign.
2. unlike signs. subtruct their absalute value & copy the sing of the bigger number.
subtructing
1. change the sign of the subrahend (if + change to - & if - change to +)
2. then go back to the rules in addition.
multiplying & dividing
1. likes signs, simply perform the operation then the answer's sign would be (+) positive
2. unlike signs, simply perform the operation then the answer's sign would be (-) negative

I am not at all sure that there are any rules that apply to integers in isolation. Any rules that exist are in the context of binary operations like addition or multiplication of integers.
There is no such thing as "solving integers". You can solve an equation, which means finding all the unknowns in that equation, but you can't solve an integer.
They become positive integers for instance - - 2 = 2
Integers are whole numbers. 1 3/4 is not a integer whereas 1 is.
The rules for addition are as follows:The sum of two negative integers is a negative integerThe sum of two positive integers is a positive integerThe rules for subtraction are as follows:If they are two positive numbers, do it normallyIf there is a negative and a positive ,change it to addition and switch the SECOND integer sign
