Hey Grandpa, can you help me with adding and subtracting decimals.
To add decimals you must first write them in a problem tower and align the decimals. Then you add zeros in any of the missing place valves how you can add.
Here is an example.
Yup
5.33+2.8=?
5.33+2.8 ?
5.33+2.80 8.13
I see, so it just like regular addition but I need to line everything correctly.
You do it the same way as adding them.
How do you subtract decimals?
Yes, that's how you do it. Make sure you regroup as well.
5.33-2.8=?
5.33-2.8 ?
So, first you need to out them in a equation tower, align the decimals, then zeroes in the empty places.
4 13 5.33- 2.80 2.53
You are welcome.
Thanks for the help Grandpa now I can complete this homework.
