Explanation:

Step1: Multiply first, then add

$2 \times 8 + 7 = 16 + 7 = 23$

Step2: Multiply first, then add

$2 + 3 \times 9 = 2 + 27 = 29$

Step3: Divide first, then add

$4 + 10 \div 2 = 4 + 5 = 9$

Step4: Subtract then add (left to right)

$9 - 2 + 3 = 7 + 3 = 10$

Step5: Solve parentheses first, then multiply

$(3 + 2) \times 9 = 5 \times 9 = 45$

Step6: Solve parentheses first, then divide

$8 \div (2 + 2) = 8 \div 4 = 2$

Step7: Divide first, then subtract

$6 \div 2 - 1 = 3 - 1 = 2$

Step8: Multiply first, then add

$1 + 3 \times 5 = 1 + 15 = 16$

Step9: Divide then multiply (left to right)

$10 \div 5 \times 2 = 2 \times 2 = 4$

Step10: Divide first, then subtract

$7 - 8 \div 2 = 7 - 4 = 3$

Answer:

1. $2 \times 8 + 7$: 23
2. $2 + 3 \times 9$: 29
3. $4 + 10 \div 2$: 9
4. $9 - 2 + 3$: 10
5. $(3 + 2) \times 9$: 45
6. $8 \div (2 + 2)$: 2
7. $6 \div 2 - 1$: 2
8. $1 + 3 \times 5$: 16
9. $10 \div 5 \times 2$: 4
10. $7 - 8 \div 2$: 3
