The answer is 500500. You just take 1000 and remove one of the zeros so it's 100. Make the 1 into a 5, and add another 500 so it makes 500500.
You can do the same for 1 plus 2 plus 3 plus 4 to 100, (which is 5050) and any other power of ten greater than 0 (like 10000, 100000, 1000000, etc.).
500,500
Its 500,500. you just work 1000 x 1001 divided by 2
Firstly ,you must do this 1000+1,so every you see this kind of question,add the last number and the first number together.So as for this,1000+1=1001 Next step is to get 1000 divide by 2 to get how many sets of 1001.And the answer is 500. Last step is 500x1001=500500. So the answer is 500500.!
500,500
1 + 2 + 3 = 6

1 + 2 + 3 + 4.99 = 10.99
1 + 2 + 3 + 4.1 = 10.1
2/3 plus 2/3 equals 4/3 or 1 1/3.
