So I'd start with F + J and to make it easier I'd just convert this to decimal which is 15 + 19 = 34 and then think about what 34 is in base 26. Well there is one 26 plus 8 more so 34 is equal to 18 in base 26.

This means that you would write 8 underneath F + J and carry a 1. Keep going like this and post your attempt if you get stuck.

EDIT: I've used the 0-9 A-P system which is not what the OP is using.

Assuming you have A=10, B=11 etc then your first number is 10 x 26^4 + 11x 26^3 + etc..

I'd write them on top of each other and use the addition algorithm you learnt in primary school.

I'm slightly confused actually. You know where yo said F + J would be 15 + 19? Wouldn't it actually be 6 + 10?

0 to 9 would be as normal then A=10, B=11 etc.

Isn't that when you are dealing with base 12?

**badmathkid**)Isn't that when you are dealing with base 12?

digits 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F with A=10, B=11...F=15

You should, of course, work with whatever convention your course uses.

EDIT: Actually this isn't the convention for base 26, see below.

Where did you get that screenshot from? The convention is to use 0-9 and then A-P but it could be that your course goes against convention!

I thought so because all the online calculators are giving me answers with numbers, i.e. F02468.

From Googling it seems like "base 26" commonly just contains 0 and letters. Okay so F + J = 6 + 10 = 16 and that is the 16th letter of the alphabet in this system which is P so you don't need to carry anything. Keep going from here.

I see. I got "EGIKMP" as an answer but on an online calculator, apparently the answer is F02468. I understand how they got that answer (using your method which completely makes sense) but which one do I use?

The online calculator is using the convention used with other bases like hexadecimal. If your lectures are teaching you to use 0, A-Z then definitely use this and ignore the online calculator.
