Try this little activity by reading it out to someone. It doesn't work as well if you actually see the numbers on the page.
Take 1000 and add 40 to it. Now add another 1000. Now add 30. And add another 1000.
Now add 20 to it. Add another 1000. Now add 10. What do you get?
Look down the page for the answer.
If you got 5000 you are with most people. Nearly everyone gets 5000.
But in reality, the answer is 4100, go ahead, check the math, it really is 4100.
How I Would Use This
There are two ideas that come to mind:
1) Always check and double check the details.
2) Once a pattern has been set up in your head it is hard to break from it.

wow that was really nice i also got the answer as 5000....I created a fun and friendly site to children, to create an interest in learning math, to treat math as fun and present it as such, to see learning as a long term proposition by working with the child to learn one topic at a time and measure his/her progress every day, to enable the child to set his/her own pace of learning and to make to every effort to support such a learning plan.
cheers,
Rosy.
