Adding several numbers

Example:
47896
83924
1785
46751
928
54
9247
21425
------
23544-
212010

We add the first column from the right, then the next etc. and then add them together:
6+4+5+1+8+4+7+5=40
9+2+8+5+2+5+4+2=37
8+9+7+7+9+2+4=46
7+3+1+6+9+1=27
4+8+4+2=18
Now we can write them under the columns like above and do all the carry overs or we add those sums together:
40
37
46
27
18
------
1111
212010

It's good practise to do both to see if one has made a mistake.
To add several numbers like 6+4+5+1+8+4+7+5=40
you look for numbers that make 10 together like 6+4 and 5+5 in this example, then you only need to add 1+8+4+7, this makes the calculations a bit easier.
