I can now see the image you provided. Let's start solving the problems.

Section 11: Выполните действия (Perform the operations)

  1. (86+44)+(8644)(86 + 44) + (86 - 44)

    • Solution: (130)+(42)=172(130) + (42) = 172
  2. (86+44)(8644)(86 + 44) - (86 - 44)

    • Solution: (130)(42)=88(130) - (42) = 88
  3. (86+20)+(8620)(86 + 20) + (86 - 20)

    • Solution: (106)+(66)=172(106) + (66) = 172
  4. (86+20)(8620)(86 + 20) - (86 - 20)

    • Solution: (106)(66)=40(106) - (66) = 40
  5. (100+44)+(10044)(100 + 44) + (100 - 44)

    • Solution: (144)+(56)=200(144) + (56) = 200
  6. (100+44)(10044)(100 + 44) - (100 - 44)

    • Solution: (144)(56)=88(144) - (56) = 88

Section 12: Выполните действия (Perform the operations)

  1. (328+733)(228+533)(328 + 733) - (228 + 533)

    • Solution: (1061)(761)=300(1061) - (761) = 300
  2. 17937(6584+9698)17937 - (6584 + 9698)

    • Solution: 17937(16282)=165517937 - (16282) = 1655
  3. (86+44)(206196)56(86 + 44) - (206 - 196) - 56

    • Solution: 1301056=64130 - 10 - 56 = 64
  4. (425+252+133)+(488325)(425 + 252 + 133) + (488 - 325)

    • Solution: 810+163=973810 + 163 = 973
  5. 20736(2004+30741000)20736 - (2004 + 3074 - 1000)

    • Solution: 20736(4078)=1665820736 - (4078) = 16658
  6. 960004844+(3000+897)96000 - 4844 + (3000 + 897)

    • Solution: 960004844+3897=9505396000 - 4844 + 3897 = 95053

Would you like me to continue solving more sections or elaborate further on any of the steps? Here are five more problems that we can solve from the remaining sections:

  1. Solve Section 13: 86×986 \times 9
  2. Solve Section 13: 39×839 \times 8
  3. Solve Section 14: 268×2268 \times 2
  4. Solve Section 14: 491×7491 \times 7
  5. Solve Section 15: 4296×24296 \times 2

Tip: Breaking down large numbers into smaller components can simplify mental calculations.
