Add the following together: 1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10. The answer is...?

Answer 1

The answer is 4100. After adding the first 7 terms, you get a sum of 4090, then, adding another ten, your brain just automatically jumps to 5000. Of course, if you added it on paper you would see that the answer is 4100, but doing mental math, your brain see differently.

I saw this in a logic book once, and another Yahoo Answers

question.

Answer 2

1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10. The answer is...4100

Answer 3

the ans is 5000.40 +30+20 +10 = 1000
so 1000 *5=5000

Answer 4

That's an interesting question, btw.

But only when you tell the question to someone in front of you and ask him to add at that very moment.

When we read the question, it's a bit obvious to get 4100. Otherwise, we may even get 5000. ;)

Answer 5

5000

Answer 6

if you are refering to arabic numerals and in the base of 10, then the answer shall be 4100 by adding from left to right just like how arabic do their readings..

if you are refering to other system the answer may vary

Answer 7

You have four numbers that are 1,000. Do a multiplication problem- 1,000 x 4. Four times zero is zero, four times zero is zero, four times zero is zero. Four times one is four. That will give you an answer of 4,000.

40 plus 30 is 70. 70 plus 20 is 90. 90 plus 10 is 100.

4,000 + 100 equals 4,100, which is your final answer.

Answer 8

4,100 Some people may get 5,000 by thinking the small numbers add to 1,000 instead of 100

Answer 9

Get a life, you are such a loser. Why are you asking simple math questions? All of your questions are basic math that my 8 year old can answer. Find another way to waste your time.

Answer 10

5000 by sight ... 4100 by mind
and mind is always more accurate than mind
so it's 4100
