Adding 5 & 6 digit numbers in columns (4 addends) worksheet for Grade 5 students.

Let’s solve each addition problem step by step. We’re adding 4 numbers in columns — some are 5-digit, some are 6-digit. We’ll add from right to left (ones place first), carrying over when needed.

Problem 1:
```
442
97,745
495,155
+932,047
----------
```

Start from the ones column:
- Ones: 2 + 5 + 5 + 7 = 19 → write down 9, carry 1
- Tens: 4 + 4 + 5 + 4 + 1 (carry) = 18 → write down 8, carry 1
- Hundreds: 4 + 7 + 1 + 0 + 1 (carry) = 13 → write down 3, carry 1
- Thousands: 0 + 7 + 5 + 2 + 1 (carry) = 15 → write down 5, carry 1
- Ten thousands: 0 + 9 + 9 + 3 + 1 (carry) = 22 → write down 2, carry 2
- Hundred thousands: 0 + 0 + 4 + 9 + 2 (carry) = 15 → write down 15

So total = 1,525,389

Wait — let me double-check with a calculator-style sum:

442 + 97,745 = 98,187
98,187 + 495,155 = 593,342
593,342 + 932,047 = 1,525,389 ✔

Problem 2:
```
42
77
9,905
+ 78,675
---------
```

Add step by step:

42 + 77 = 119
119 + 9,905 = 10,024
10,024 + 78,675 = 88,699

Check column-wise:

Ones: 2+7+5+5=19 → 9, carry 1
Tens: 4+7+0+7+1=19 → 9, carry 1
Hundreds: 0+0+9+6+1=16 → 6, carry 1
Thousands: 0+0+9+8+1=18 → 8, carry 1
Ten thousands: 0+0+0+7+1=8 → 8

→ 88,699 ✔

Problem 3:
```
20
18
650,958
+203,416
----------
```

20 + 18 = 38
38 + 650,958 = 650,996
650,996 + 203,416 = 854,412

Column check:

Ones: 0+8+8+6=22 → 2, carry 2
Tens: 2+1+5+1+2=11 → 1, carry 1
Hundreds: 0+0+9+4+1=14 → 4, carry 1
Thousands: 0+0+0+3+1=4
Ten thousands: 0+0+5+0=5
Hundred thousands: 0+0+6+2=8

→ 854,412 ✔

Problem 4:
```
611
52,718
5,638
+ 381
--------
```

611 + 52,718 = 53,329
53,329 + 5,638 = 58,967
58,967 + 381 = 59,348

Column check:

Ones: 1+8+8+1=18 → 8, carry 1
Tens: 1+1+3+8+1=14 → 4, carry 1
Hundreds: 6+7+6+3+1=23 → 3, carry 2
Thousands: 0+2+5+0+2=9
Ten thousands: 0+5+0+0=5

→ 59,348 ✔

Problem 5:
```
7,871
129,136
4,306
+851,640
----------
```

7,871 + 129,136 = 137,007
137,007 + 4,306 = 141,313
141,313 + 851,640 = 992,953

Column check:

Ones: 1+6+6+0=13 → 3, carry 1
Tens: 7+3+0+4+1=15 → 5, carry 1
Hundreds: 8+1+3+6+1=19 → 9, carry 1
Thousands: 7+9+4+1+1=22 → 2, carry 2
Ten thousands: 0+2+0+5+2=9
Hundred thousands: 0+1+0+8=9

→ 992,953 ✔

Problem 6:
```
47
65,361
20
+ 26
--------
```

47 + 65,361 = 65,408
65,408 + 20 = 65,428
65,428 + 26 = 65,454

Column check:

Ones: 7+1+0+6=14 → 4, carry 1
Tens: 4+6+2+2+1=15 → 5, carry 1
Hundreds: 0+3+0+0+1=4
Thousands: 0+5=5
Ten thousands: 0+6=6

→ 65,454 ✔

Problem 7:
```
75
358
372
+673,148
----------
```

75 + 358 = 433
433 + 372 = 805
805 + 673,148 = 673,953

Column check:

Ones: 5+8+2+8=23 → 3, carry 2
Tens: 7+5+7+4+2=25 → 5, carry 2
Hundreds: 0+3+3+1+2=9

Problem 8:
```
6,369
45,245
42,091
+ 685

6,369 + 45,245 = 51,614
51,614 + 42,091 = 93,705
93,705 + 685 = 94,390

Column check:

Ones: 9+5+1+5=20 → 0, carry 2
Tens: 6+4+9+8+2=29 → 9, carry 2
Hundreds: 3+2+0+6+2=13 → 3, carry 1
Thousands: 6+5+2+0+1=14 → 4, carry 1
