These examples will help you get used to doing column math. You will use what you learned in Basic Addition.

Here's an example:

2
3
+
5
6

White Box   White Box

Right To Left. We first see the 3, which is above the 6.  3 + 6 = 9. Our equation is now:

2
3
+
5
6

White Box   White Box

Again we go from Right To Left and see the 2, which is above the 5.  2 + 5 = 7. Our equation is now:

2
3
+
5
6

White Box   White Box

Here's another example:

4
2
1
+
1
7
6

White Box   White Box   White Box

Right To Left. We first see the 1, which is above the 6.  1 + 6 = 7. Our equation is now:

4
2
1
+
1
7
6

White Box   White Box   White Box

Again we go from Right To Left and see the 2, which is above the 7.  2 + 7 = 9. Our equation is now:

4
2
1
+
1
7
6

White Box   White Box   White Box

Yet again we go from Right To Left and see the 4, which is above the 1.  4 + 1 = 5. Our equation is now:

4
2
1
+
1
7
6

White Box   White Box   White Box

Here's one more example. This example uses four columns:

8
6
2
3
+
1
0
5
6

White Box   White Box   White Box   White Box

Right To Left. We first see the 3, which is above the 6.  3 + 6 = 9. Our equation is now:

8
6
2
3
+
1
0
5
6

White Box   White Box   White Box   White Box

Again we go from Right To Left and see the 2, which is above the 5.  2 + 5 = 7. Our equation is now:

8
6
2
3
+
1
0
5
6

White Box   White Box   White Box   White Box

Yet again we go from Right To Left and see the 6, which is above the 0.  6 + 0 = 6. Our equation is now:

8
6
2
3
+
1
0
5
6

White Box   White Box   White Box   White Box

One last time we go from Right To Left and see the 8, which is above the 1.  8 + 1 = 9. Our equation is now:

8
6
2
3
+
1
0
5
6
