yes, another one.
what is this?
1x1+1x0+1x2+1x0
note that it is not adding the answers of all of them as an answer

This appear to be a series, the next term are +1x3+1x0+1x4+1x0 etc..
The solutionn of this equation in the rational set of numbers, is found by grouping the terms:
(1x1+1x2+1x3+...1xn)+ (1x0+1x0+1x0...),
We know that the answer of the 2nd term is 0 as 1x0=0 and adding as many times as you want the answer will remain 0 (zero).
For the first term as "n" is defined say n=100 then adding all the numbers fron 1 to 100= n+(n+1)/2 or (100+101)/2 which is [b]5050[/b].
If you do not define "n" then the series diverges and does not have a finite limit.
Conversely a convergent series has a finite number.
nope but it is four numbers
1x1+1x0+1x2+1x0 END too slow.
I was thinking of:
1x1=1
1x0=0
1x2=2
1x0=0
1020
another one:
1, 7, 49, 343, ?, 16807

Try this one:
2, 1, 3, 4, 7, 11, ?
18 (like the fibonacci)
The reason you do multiplication first is because multiplications is the abbreviation of a Sum
2+2+2=2x3=6
1+6=7
2+2+2=2x3=6
1+6=7

What is 1+2x3?
