Addition , Subtraction and Multiplication worksheet - Free Printable

Problem Description:

The image contains three sections: Addition, Subtraction, and Multiplication. Each section has a set of problems that need to be solved. Let's solve each problem step by step.

---

Section 1: Addition

#### Problem 1: \( 996 + 978 \)
1. Align the numbers by place value:
```
996
+ 978
------
```
2. Add column by column from right to left:
- Units place: \( 6 + 8 = 14 \). Write down 4 and carry over 1.
- Tens place: \( 9 + 7 + 1 (\text{carry}) = 17 \). Write down 7 and carry over 1.
- Hundreds place: \( 9 + 9 + 1 (\text{carry}) = 19 \). Write down 9 and carry over 1.
- Thousands place: \( 0 + 0 + 1 (\text{carry}) = 1 \).

Final result: \( 1974 \).

#### Problem 2: \( 896 + 968 \)
1. Align the numbers by place value:
```
896
+ 968
------
```
2. Add column by column from right to left:
- Units place: \( 6 + 8 = 14 \). Write down 4 and carry over 1.
- Tens place: \( 9 + 6 + 1 (\text{carry}) = 16 \). Write down 6 and carry over 1.
- Hundreds place: \( 8 + 9 + 1 (\text{carry}) = 18 \). Write down 8 and carry over 1.
- Thousands place: \( 0 + 0 + 1 (\text{carry}) = 1 \).

Final result: \( 1864 \).

#### Problem 3: \( 795 + 998 \)
1. Align the numbers by place value:
```
795
+ 998
------
```
2. Add column by column from right to left:
- Units place: \( 5 + 8 = 13 \). Write down 3 and carry over 1.
- Tens place: \( 9 + 9 + 1 (\text{carry}) = 19 \). Write down 9 and carry over 1.
- Hundreds place: \( 7 + 9 + 1 (\text{carry}) = 17 \). Write down 7 and carry over 1.
- Thousands place: \( 0 + 0 + 1 (\text{carry}) = 1 \).

Final result: \( 1793 \).

Section 2: Subtraction

#### Problem 1: \( 926 - 658 \)
1. Align the numbers by place value:
```
926
- 658
------
```
2. Subtract column by column from right to left:
- Units place: \( 6 - 8 \). Borrow 1 from the tens place, making it \( 16 - 8 = 8 \).
- Tens place: After borrowing, \( 1 (from 2) - 5 = -4 \). Borrow 1 from the hundreds place, making it \( 11 - 5 = 6 \).
- Hundreds place: After borrowing, \( 8 (from 9) - 6 = 2 \).

Final result: \( 268 \).

#### Problem 2: \( 835 - 368 \)
1. Align the numbers by place value:
```
835
- 368
------
```
2. Subtract column by column from right to left:
- Units place: \( 5 - 8 \). Borrow 1 from the tens place, making it \( 15 - 8 = 7 \).
- Tens place: After borrowing, \( 2 (from 3) - 6 = -4 \). Borrow 1 from the hundreds place, making it \( 12 - 6 = 6 \).
- Hundreds place: After borrowing, \( 7 (from 8) - 3 = 4 \).

Final result: \( 467 \).

#### Problem 3: \( 956 - 598 \)
1. Align the numbers by place value:
```
956
- 598
------
```
2. Subtract column by column from right to left:
- Units place: \( 6 - 8 \). Borrow 1 from the tens place, making it \( 16 - 8 = 8 \).
- Tens place: After borrowing, \( 4 (from 5) - 9 = -5 \). Borrow 1 from the hundreds place, making it \( 14 - 9 = 5 \).
- Hundreds place: After borrowing, \( 8 (from 9) - 5 = 3 \).

Final result: \( 358 \).

Section 3: Multiplication

#### Problem 1: \( 21 \times 2 \)
1. Multiply each digit of 21 by 2:
- \( 1 \times 2 = 2 \)
- \( 2 \times 2 = 4 \)

Final result: \( 42 \).

#### Problem 2: \( 42 \times 2 \)
1. Multiply each digit of 42 by 2:
- \( 2 \times 2 = 4 \)
- \( 4 \times 2 = 8 \)

Final result: \( 84 \).

#### Problem 3: \( 53 \times 2 \)
1. Multiply each digit of 53 by 2:
- \( 3 \times 2 = 6 \)
- \( 5 \times 2 = 10 \). Write down 0 and carry over 1.
- Add the carry to the next place: \( 1 + 0 = 1 \).

Final result: \( 106 \).

#### Problem 4: \( 84 \times 2 \)
1. Multiply each digit of 84 by 2:
- \( 4 \times 2 = 8 \)
- \( 8 \times 2 = 16 \). Write down 6 and carry over 1.
- Add the carry to the next place: \( 1 + 0 = 1 \).

Final result: \( 168 \).
