Question

EXERCISE - 5.4
Solve the given problems using BODMAS:
1. 25 + (7 - 2) × 5
2. 50 - 3 x 5
3. 10 - (1 + 3 x 2)
4. 40 : (5 + 3 x 5)
5. 81 + (6 + 3)
6, 4 x 7 + 10 = 2​

Answer 1

Step-by-step explanation:

.1. $25 + (7 - 2) \times 5 \\ = 25 + 25 \\ = 50$

2. $50 - 3 \times 5 \\ = 50 - 15 \\ = 35$

3. $10 - (1 + 3 \times 2) \\ = 10 - (7) \\ = 3$

4. $40 \div (5 + 3 \times 5) \\ = 40 \div (20) \\ = 2$

5. $81 + (6 + 3) \\ = 81 + 9 \\ = 90$

6. $4 \times 7 + 10 - 2 \\ = 28 + 10 - 2 \\ = 36$
