Adding integers either negative or positive,
Adding integer is easy yet hard for some people, here we will show you how to add decimal negative and not negative.
When you are adding positive decimals you are going into the left
--> for example 1
2.1
4.9
----
7.0 or 7 since it is a positive it makes a positive, but if it is a negative you take it away like this:
4.9
-2.1
-----
2.8 but it is a positive because the negative number was not enough to take away all the number. If it is a negative decimal plus a negative decimal then the answer would be
-4.9
-2.1
-----
-7 or -7.0
You will see that it is like normal adding except it is negatives and it is in decimals, since the decimals you are using to subtract are negatives then the answer would be in decimals. But the answer still depends on the numbers making them either negative or positive.
