Answer 3

а) To solve the addition problem 5421 + 2356, we can write the numbers vertically and add each column starting from the right:

   5421
+ 2356
-------

Starting from the rightmost column, we add 1 + 6, which equals 7. Then we move to the next column and add 2 + 5, which equals 7 as well. Continuing this process, we have 4 + 3, which equals 7, and finally 5 + 2, which equals 7. Therefore, the sum of 5421 and 2356 is 7777.

б) To solve the subtraction problem 56 + 395 - 20 + 744, we can write the numbers vertically and subtract each column starting from the right:

    56
  + 395
  -  20
  + 744
-------

Starting from the rightmost column, we add 6 + 5, which equals 11. We write down the 1 and carry over the 10 to the next column. Then we subtract 1 (from the carryover) from 9, which equals 8. Moving to the next column, we add 1 + 3 + 2 (from the carryover), which equals 6. Finally, we add 0 + 7 + 4, which equals 11. Therefore, the result of the addition and subtraction is 811.

в) To solve the addition and subtraction problem 240 + 506 - 239 + 496, we can write the numbers vertically and perform the calculations column by column:

   240
+ 506
- 239
+ 496
------

Starting from the rightmost column, we add 0 + 6 - 9 + 6, which equals 3. Moving to the next column, we add 4 + 0 + 3 + 9, which equals 16. We write down the 6 and carry over the 1 to the next column. Then we add 2 + 5 + 2 + 4 (from the carryover), which equals 13. We write down the 3 and carry over the 1 to the next column. Finally, we add 2 + 0 + 0 + 4 (from the carryover), which equals 6. Therefore, the result of the addition and subtraction is 636.

Please note that the above calculations are based on the given numbers and the standard rules of addition and subtraction.
