CBSE Class 2 Math Tens and Ones Worksheet with Solutions - Free Printable

Let’s solve each part step by step.

---

Q1: Write the standard form

This means turning “tens and ones” into a regular number.

- 6 tens + 8 ones = 60 + 8 = 68
- 9 tens + 6 ones = 90 + 6 = 96
- 4 tens + 3 ones = 40 + 3 = 43
- 6 tens + 0 ones = 60 + 0 = 60
- 2 tens + 6 ones = 20 + 6 = 26

✔ All correct.

Q2: Add ones and tens with carry

We add column by column, starting from the right (ones place). If the sum is 10 or more, we carry over to the tens place.

Let’s do each one:

1.
```
67
+ 45
----
Ones: 7 + 5 = 12 → write 2, carry 1
Tens: 6 + 4 + 1 = 11 → write 11
→ 112
```

2.
```
84
+ 79
----
Ones: 4 + 9 = 13 → write 3, carry 1
Tens: 8 + 7 + 1 = 16 → write 16
→ 163
```

3.
```
87
+ 56
----
Ones: 7 + 6 = 13 → write 3, carry 1
Tens: 8 + 5 + 1 = 14 → write 14
→ 143
```

4.
```
77
+ 56
----
Ones: 7 + 6 = 13 → write 3, carry 1
Tens: 7 + 5 + 1 = 13 → write 13
→ 133
```

5.
```
49
+ 86
----
Ones: 9 + 6 = 15 → write 5, carry 1
Tens: 4 + 8 + 1 = 13 → write 13
→ 135
```

6.
```
68
+ 57
----
Ones: 8 + 7 = 15 → write 5, carry 1
Tens: 6 + 5 + 1 = 12 → write 12
→ 125
```

7.
```
66
+ 46
----
Ones: 6 + 6 = 12 → write 2, carry 1
Tens: 6 + 4 + 1 = 11 → write 11
→ 112
```

8.
```
87
+ 59
----
Ones: 7 + 9 = 16 → write 6, carry 1
Tens: 8 + 5 + 1 = 14 → write 14
→ 146
```

✔ All addition problems solved correctly.

Q3: Subtract with borrow

When the top digit in the ones place is smaller than the bottom, we borrow 1 ten (which becomes 10 ones).

Let’s go one by one:

1.
```
64
- 27
----
Ones: 4 < 7 → borrow from tens. 6 becomes 5, 4 becomes 14.
14 - 7 = 7
Tens: 5 - 2 = 3
→ 37
```

2.
```
75
- 47
----
Ones: 5 < 7 → borrow. 7 becomes 6, 5 becomes 15.
15 - 7 = 8
Tens: 6 - 4 = 2
→ 28
```

3.
```
87
- 69
----
Ones: 7 < 9 → borrow. 8 becomes 7, 7 becomes 17.
17 - 9 = 8
Tens: 7 - 6 = 1
→ 18
```

4.
```
75
- 39
----
Ones: 5 < 9 → borrow. 7 becomes 6, 5 becomes 15.
15 - 9 = 6
Tens: 6 - 3 = 3
→ 36
```

5.
```
78
- 29
----
Ones: 8 < 9 → borrow. 7 becomes 6, 8 becomes 18.
18 - 9 = 9
Tens: 6 - 2 = 4
→ 49
```

6.
```
65
- 29
----
Ones: 5 < 9 → borrow. 6 becomes 5, 5 becomes 15.
15 - 9 = 6
Tens: 5 - 2 = 3
→ 36
```

✔ All subtraction problems solved correctly.
