When adding integers with the same sign, you the numbers and the sign. when adding integers with different signs you the numbers and use the sign of the absolute value

(I)

we are given when we add numbers of same sign

For exp: +2+3=+5

-2-3=-5

We can see that we are adding numbers and then we put same sign in front

so, we can fill spaces

When adding integers with the same sign, you add the numbers and put the sign

(II)

we are given when we add numbers of different signs

For exp: 2-3=-1

-2+3=+1

We can see that we are subtracting numbers and then we put sign of largest value in front

so, we can fill spaces

When adding integers with different signs you subtract the numbers and use the sign of the largest absolute value
