Calculate the results of the given arithmetic operations.

Mathematical Calculations

The image displays several arithmetic operations. Below are the calculations based on the visible numbers:

Operation 1: Addition/Subtraction (Top section)

Based on the visible digits, it appears to be a series of additions and subtractions, possibly intermediate steps in a larger problem.

   1780 + 3 = 1783
  15263 + 4 = 15267
  20351 + 2 = 20353
40220556 + 130 = 40220686

Operation 2: Multiplication (Middle section)

A multiplication problem is set up.

   40576
 x   38200
 ---------
  8115200 (This appears to be a partial product or an incorrect calculation)

Let's perform the multiplication correctly:

      40576
  x   38200
  -----------
      00000  (40576 * 0)
     00000   (40576 * 0)
    81152    (40576 * 2)
   324608     (40576 * 8)
+ 121728      (40576 * 3)
-----------
  1549992000

The number '81152' written below the line '40576 x 38200' seems to be an intermediate step or an incorrect result.

Operation 3: Other Calculations (Bottom left)

These appear to be separate calculations or a different problem.

   50
 + 40
 ----
    0

This calculation also seems incomplete or incorrect as written. If it's 50 + 40, the result is 90.

   0
  00
 +00
 ----
  000

This is likely representing 0 + 0 + 0, resulting in 0.

Summary of Calculations:

• Top section appears to be additions: 1783, 15267, 20353, 40220686.


• Middle section is a multiplication of 40576 by 38200, with the correct result being 1,549,992,000. The handwritten intermediate calculation '81152' is likely incorrect or incomplete.


• Bottom left shows simple additions with results possibly intended to be 90 and 0.
