When you are adding a negative number to a positive number, try thinking through it this way:
Take two steps backwards then five steps forward. Where are you in relationship to where you started?

if u have problems adding and subbtructing negative numbers use a number line; for example, --- -2-- -1-- 0---1---2---3---4----5--
naw start counting from -2 five times to the right then stop. the result is going to be 3. if it is -2-5 u go to the the left then u will see -7. That is not the best way, but it gives u general ideas. use this for large nnumbers -123+130= 130-123= 7

3. Think of subtracting 2 from 5: 5 - 2 = 3

no, the answer is 3.
---i have no idea how you get -4. its the same as taking 5-2. 5 -2=3.

no its 3 . you have to do -2+5 so then you would add 2 to make it 0 then add the 3 that is left and that makes 3. not negative 4

The answer would be 3. Positive numbers and negative numbers can be changed around, so just think of 5-2+

it is 3. When addina a positive and negative number you take -2 and make it +2, then subtract 5 and 2! Viola! 3!

We know the commutative property holds... thus
-2 + 5 is equivalent to 5 - 2
which is commonly thought to be 3
