We need your honesty in this trick.....
Do the following addition problem by saying aloud the partial sums.
Start with 1000.
Add 40 to it.
Now add another 1000.
Now add 30.
Add another 1000.
Now add 20.
Now add another 1000.
Now add 10.
--------------------------------
What is the total?
Do not look down and cheat....

No, it is not 5,000!
The sum is 4,100.
(Check your place value)
4,090 + 10 = 4,100.
