- Write the numbers one on top of the other right aligned (so that the last (unit) digit of each number line up in a column)
- Starting with the unit (rightmost) digits of the numbers and no carry
- Add the digits together with the carry (if any)
- write the units digit of the sum under the digits just added
- if the result is more than nine, note a carry of one (1) otherwise note no carry
- go to the next digits to the left of the ones just added
- If there is no next digit in both of the numbers and no carry then stop
- if either number has run out of digits, then take the digit to be zero (0)
- go to step 3

When you add two positive integers will the sum always be positive or negative?
It will always be positive.
When you add two positive integers their sum is always a positive integers when you subtract two positive integers is their difference always a positive integer?
diffrence will always be positive except when it is zero but is you speak of substraction operation it can be positive negative or zero
When you add two integers how can you decide whether it is a positive negative or zero?
That will depend on the two integers that you use. The result could be any of negative, zero or positive.
What are the rules for adding and subtracting integers?
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
The sum of two negative integers is a positive integer?
No, the sum of two negative integers is not a positive integer. For example, if you add -5 and -6 together the sum would be -11.
