MAKE THIS WITHOUT A CALCULATOR 
This “simple” math problem keeps fooling thousands of people online because almost everyone’s brain makes the exact same mistake.
Try solving it in your head only — no calculator allowed 
You have:
1000
- 40
- 1000
- 30
- 1000
- 20
- 1000
- 10
What’s the answer? 
Most people instantly say 5,000…
But that’s actually WRONG.
The correct answer is:
4,100
Here’s why people get tricked:
Your brain starts recognizing the repeated pattern of “+1000” and unconsciously jumps ahead before fully processing the smaller numbers. By the time you reach 4,090 and add 10, many people mentally “round up” to 5,000 without realizing it.
The real math is:
1000 + 40 = 1040
- 1000 = 2040
- 30 = 2070
- 1000 = 3070
- 20 = 3090
- 1000 = 4090
- 10 = 4100
Did you get it right the first time?
