Can you get the numbers 1,2,3,4,5, 6, 7, 8,9 to total 100 just by adding together ?
People keep saying it cannot be done but it can .
I posted this question up on different sites in the past at one stage it caused several savage exchanges with a group of mathematicians who got totally cheesed off and claimed it was insoluble all because they couldn't solve it ; incidentally I've yet to have anyone get the correct solution....
No decimal points or any such methods are used the question is stated simply but yet I’m usually bombarded with a series of further questions , then temper tantrums and sometimes threats of violence

You see, there are 9 numbers in the pattern, keep this in mind, as I descend the order.
There are 9 terms, so 9+9
Now there are 8 left, so 8+8,
And So on
9+9+8+8+7+7+6+6+5+5+4+4+3+3+2+2+1 (Don't add one here, because there is only one left in the sequence!)
All that = 91, and since there are 9 numbers in the sequence, 91+9=100
Done....

No, if you limit yourself to Nine Whole Numbers 1-9, and then limit yourself to addition, it is not possible to reach 100.

10+11+12+13+14+15+16+17+18+19 = 145
Now use the single digits away from zero and add > 0+1+2+3+4+5+6+7+8+9 > 45

No, logically, it is not possible.
You would have to add another function for it to work.
Like I said, you can show this, as these are small Real Number
I
II
III
IIII
IIIII
IIIII I
IIIII II
IIIII III
IIIII IIII
45
You cannot increase the number of tallies, addition cannot result in the sum being greater than its components.
IF you add another function, you can get it to work.
