Step-by-step solution for: Bodmas | PreetiGulliya
To solve the given problems, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Since there are no parentheses or exponents in these problems, we will focus on multiplication and division first, followed by addition and subtraction.
Let's solve each problem step by step:
---
1. Perform multiplication first: \( 8 \times 10 = 80 \).
2. Then add: \( 22 + 80 = 102 \).
Answer: \( 102 \)
---
1. Perform multiplication first: \( 4 \times 3 = 12 \).
2. Substitute back: \( 25 - 12 + 22 \).
3. Perform subtraction and addition from left to right:
- \( 25 - 12 = 13 \).
- \( 13 + 22 = 35 \).
Answer: \( 35 \)
---
1. Perform multiplication first: \( 8 \times 5 = 40 \).
2. Substitute back: \( 28 + 7 + 40 \).
3. Perform addition from left to right:
- \( 28 + 7 = 35 \).
- \( 35 + 40 = 75 \).
Answer: \( 75 \)
---
1. Perform multiplication first: \( 16 \times 2 = 32 \).
2. Substitute back: \( 32 + 30 + 6 \).
3. Perform addition from left to right:
- \( 32 + 30 = 62 \).
- \( 62 + 6 = 68 \).
Answer: \( 68 \)
---
1. Perform multiplication first: \( 6 \times 3 = 18 \).
2. Substitute back: \( 82 + 18 + 20 \).
3. Perform addition from left to right:
- \( 82 + 18 = 100 \).
- \( 100 + 20 = 120 \).
Answer: \( 120 \)
---
1. Perform multiplication first: \( 6 \times 7 = 42 \).
2. Substitute back: \( 36 + 42 \).
3. Perform addition: \( 36 + 42 = 78 \).
Answer: \( 78 \)
---
1. Perform multiplication first: \( 9 \times 4 = 36 \).
2. Substitute back: \( 42 + 36 + 10 \).
3. Perform addition from left to right:
- \( 42 + 36 = 78 \).
- \( 78 + 10 = 88 \).
Answer: \( 88 \)
---
1. Perform both multiplications first:
- \( 5 \times 5 = 25 \).
- \( 8 \times 3 = 24 \).
2. Substitute back: \( 25 + 24 \).
3. Perform addition: \( 25 + 24 = 49 \).
Answer: \( 49 \)
---
1. Perform multiplication first: \( 7 \times 6 = 42 \).
2. Substitute back: \( 55 + 11 + 42 \).
3. Perform addition from left to right:
- \( 55 + 11 = 66 \).
- \( 66 + 42 = 108 \).
Answer: \( 108 \)
---
1. Perform multiplication first: \( 8 \times 3 = 24 \).
2. Substitute back: \( 17 + 24 \).
3. Perform addition: \( 17 + 24 = 41 \).
Answer: \( 41 \)
---
1. \( 102 \)
2. \( 35 \)
3. \( 75 \)
4. \( 68 \)
5. \( 120 \)
6. \( 78 \)
7. \( 88 \)
8. \( 49 \)
9. \( 108 \)
10. \( 41 \)
