Let's solve each of the problems step by step from the image. I'll go through the calculations in sequence:

1. **(2 × 12) × (240 + 112)**
   \[
   = 24 × 352 = 8448
   \]

2. **(999 ÷ 333) × (3 × 13)**
   \[
   = 3 × 39 = 117
   \]

3. **(910 - 776) × (8 × 8)**
   \[
   = 134 × 64 = 8576
   \]

4. **(245 + 667) ÷ (21 + 17)**
   \[
   = 912 ÷ 38 = 24
   \]

5. **(960 ÷ 4) ÷ (17 - 14)**
   \[
   = 240 ÷ 3 = 80
   \]

6. **(894 + 888) ÷ (40 - 22)**
   \[
   = 1782 ÷ 18 = 99
   \]

7. **(843 + 123) ÷ (28 ÷ 2)**
   \[
   = 966 ÷ 14 = 69
   \]

8. **(2 × 11) × (406 - 144)**
   \[
   = 22 × 262 = 5764
   \]

9. **(15 × 9) × (300 - 262)**
   \[
   = 135 × 38 = 5130
   \]

10. **(387 - 223) × (18 ÷ 6)**
    \[
    = 164 × 3 = 492
    \]

11. **(145 - 123) × (8 × 15)**
    \[
    = 22 × 120 = 2640
    \]

12. **(2 × 1890) ÷ (27 + 15)**
    \[
    = 3780 ÷ 42 = 90
    \]

13. **(5 × 528) ÷ (12 + 32)**
    \[
    = 2640 ÷ 44 = 60
    \]

14. **(125 + 115) ÷ (96 ÷ 4)**
    \[
    = 240 ÷ 24 = 10
    \]

15. **(345 + 843) ÷ (3 × 6)**
    \[
    = 1188 ÷ 18 = 66
    \]

16. **(213 - 104) × (12 × 3)**
    \[
    = 109 × 36 = 3924
    \]

17. **(288 - 167) × (100 - 65)**
    \[
    = 121 × 35 = 4235
    \]

18. **(96 ÷ 8) × (11 + 49)**
    \[
    = 12 × 60 = 720
    \]

19. **(4 × 660) ÷ (12 + 36)**
    \[
    = 2640 ÷ 48 = 55
    \]

Do you need more detailed steps on any of these problems?

Here are 5 questions to help you explore further:
1. What is the order of operations used in each calculation?
2. How would the result change if you modify one of the numbers in the equations?
3. Why is it important to solve the brackets first in these problems?
4. Can you identify which operations result in larger numbers?
5. How do division and multiplication affect the overall solution compared to addition and subtraction?

**Tip:** Always solve expressions inside parentheses first, then proceed with multiplication, division, addition, and subtraction (PEMDAS rule).

Calculate the following mixed operations with brackets: (2 × 12) × (240 + 112), (999 ÷ 333) × (3 × 13), (910 - 776) × (8 × 8), and other similar expressions.

Practice solving arithmetic problems that involve mixed operations with brackets. Learn how to apply the correct order of operations (PEMDAS) to solve problems accurately. Suitable for students in Grades 5-7.
