which is an error of addition by one.
Thus, this option is correct.
(B)The given example is:
[tex]3415 + 2174[/tex]
Adding these two numbers, we get
[tex]6589[/tex]
which is an error of addition by one.
Thus, this option is correct.
(C)The given example is:
[tex]5167+4622[/tex]
Adding these two numbers, we get
[tex]9789[/tex]
which is not an error of addition by one.
Thus, this option is not correct.
(D) The given example is:
[tex]2683+6215[/tex]
Adding these two numbers, we get
