Addition with 5 and 6 digit numbers worksheet for educational use.

Let’s solve each addition problem step by step. We’ll add the numbers column by column, starting from the right (ones place), and carry over if needed.

Problem 1:
```
6 2 1 8 8
+ 3 5 0 6 5 0
+ 4 9 3 9 1
+ 2 5 9 2 0 4
-------------
```

Align them properly:

```
6 2 1 8 8
3 5 0 6 5 0
4 9 3 9 1
+ 2 5 9 2 0 4
---------------
```

Add column by column from right to left:

Ones place:
8 + 0 + 1 + 4 = 13 → write 3, carry 1

Tens place:
8 + 5 + 9 + 0 + 1 (carry) = 23 → write 3, carry 2

Hundreds place:
1 + 6 + 3 + 2 + 2 (carry) = 14 → write 4, carry 1

Thousands place:
2 + 0 + 9 + 9 + 1 (carry) = 21 → write 1, carry 2

Ten thousands place:
6 + 5 + 4 + 5 + 2 (carry) = 22 → write 2, carry 2

Hundred thousands place:
3 + 2 + 2 (carry) = 7

→ Final sum: 721433

Wait — let me double-check alignment. Actually, first number is 5-digit, others are 6-digit? Let's align with leading zeros for clarity:

Actually, better to stack as:

```
0 6 2 1 8 8
3 5 0 6 5 0
0 4 9 3 9 1
+ 2 5 9 2 0 4
-----------------
```

Now add:

Ones: 8+0+1+4 = 13 → 3, carry 1
Tens: 8+5+9+0 +1 = 23 → 3, carry 2
Hundreds: 1+6+3+2 +2 = 14 → 4, carry 1
Thousands: 2+0+9+9 +1 = 21 → 1, carry 2
Ten-thousands: 6+5+4+5 +2 = 22 → 2, carry 2
Hundred-thousands: 0+3+0+2 +2 = 7

→ 721,433

✔ Correct.

Problem 2:
```
7 1 7 8 5 6
1 8 5 2 1 5
5 4 8 3 8
+ 3 5 0 1 2 6
-------------
```

Align:

```
7 1 7 8 5 6
1 8 5 2 1 5
0 5 4 8 3 8
+ 3 5 0 1 2 6
----------------
```

Add:

Ones: 6+5+8+6 = 25 → 5, carry 2
Tens: 5+1+3+2 +2 = 13 → 3, carry 1
Hundreds: 8+2+8+1 +1 = 20 → 0, carry 2
Thousands: 7+5+4+0 +2 = 18 → 8, carry 1
Ten-thousands: 1+8+5+5 +1 = 20 → 0, carry 2
Hundred-thousands: 7+1+0+3 +2 = 13 → 3, carry 1? Wait — no more digits, so just 13? But we have 6 columns max.

Wait — actually, all numbers are 6-digit or less. Let’s do it carefully:

Write with 6 digits:

Row1: 717856
Row2: 185215
Row3: 054838
Row4: 350126

Add:

Start from right:

Column 1 (ones): 6+5+8+6 = 25 → 5, carry 2
Column 2 (tens): 5+1+3+2 +2 = 13 → 3, carry 1
Column 3 (hundreds): 8+2+8+1 +1 = 20 → 0, carry 2
Column 4 (thousands): 7+5+4+0 +2 = 18 → 8, carry 1
Column 5 (ten-thousands): 1+8+5+5 +1 = 20 → 0, carry 2
Column 6 (hundred-thousands): 7+1+0+3 +2 = 13 → 3, carry 1 → but that would be million? So total is 1,308,035?

Wait — let’s compute numerically:

717856
+185215 = 903071
+54838 = 957909
+350126 = 1,308,035 ✔

So answer: 1,308,035

But in grid format, we should write without commas: 1308035

Problem 3:
```
4 0 3 6 0 5
6 2 3 4 2
5 2 1 7 3 4

-------------
```

Align:

```
4 0 3 6 0 5
0 6 2 3 4 2
5 2 1 7 3 4

Ten-thousands: 0+6+2+6 +1 = 15 → 5, carry 1
Hundred-thousands: 4+0+5+3 +1 = 13 → 3, carry 1 → so 1,352,301?

Check numerically:

403605
+62342 = 465947
+521734 = 987681
+364620 = 1,352,301 ✔
