Sum of rows does not tie to sum of columns

[Guest]

A B C
D
1 69,500.00 156,800.00 141,108.00 367,408.00
2 100,857.90 110,228.80 89,602.96 300,689.66
3 13,273.88 53,709.90 - 66,983.78
4 (44,631.78) (7,138.70) 51,505.04 (265.44)

A1-A2-A3=A4, B1-B2-B3=B4, C1-C2-C3=C4

A4+B4+C4=D4

When I add a check formula to verify that (D1-D2-D3=D4)=D4 I get an error
message. I found that although there are not an additional numbers beyond
the 2 decimal places seen in each cell, when I extend the decimal places of
C4 out to about 13 it shows 265.44000000000200 and D1-D2-D3=
265.44000000003100.
What is causing these decimal problems? The numbers in cells A1 thru C3
were typed in just as shown above with at most two decimal points.

Thanks for the quick response. I have read the item cited, however, I do not
understand how this can be a rounding problem in the first place since the
numbers were entered with no more than two decimal places and only simple
addition or subtraction was applied. How can I then end up with a sum that
has some arbitrary decimal number out to 13 or 14 decimal places? There was
no division done or percentages or anything else that would introduce the
results stated in the original post. What am I missing?
