So I found this hat formula today and decided to make up my own patterns for my family for knitted hats this winter.  Anyways, it's just a basic hat formula and I have everything figured except I can't figure out what "E" is.  By that I mean that I am not understanding what "E" is suppose to represent. (Maybe it's because I'm bad at math, or maybe I'm just misunderstanding what they want me to do).

Here is what I have so far.

Based on there formula
Knitted swatch = 18sts "A"
Head measurement (minus 2" for a snugger fit) 18" "B"
"A" times "B" = 324 but I rounded down to 320 for "C"
Dividing "C" by 4 gives me 80 which is the number I need to cast on for "D"

Now, the part that I'm confused about is "E" because the difference between "C" and "D" is 240.  What in the world would they mean by this part here

(directly taken from website to show what I'm talking about)

increase or decrease "E" so that you have "C" stitches on the needle

Any help with this part will be greatly appreciated.  Thank you so much!

Difference means subtract so it's C - D.  D isn't 80, it's the number that you round C to to make it divisible by 4 so your 2x2 ribbing will come out evenly.  You can just use 320 sinct that's divisible by 10 and 4.

I was confused too at first, but change the words 'divisible by 4"  to "multiple of 4" and it makes sense (to me anyway  Cheesy)

So, using your numbers ...

C = 324, rounded to 320 to be divisible by 10
D = C plus or minus a few stitches to be a multiple of 4, but 320 already is a multiple of 4 (4x80 = 320) so don't do anything and D = 320

E = C (324) - D (324) = zero

Cast on C (324), do ribbing, then increase E (zero - so no increase) to get to D.

If C was 323, then D would be 320 (since 323 isn't divisible by 4) and E would be 3. Cast on 320, do ribbing, then increase 3 st.

Does that help?

Waitamminnit everyone! 320 sts is far too many to co for a hat!

multicrafter, look at the formula again - A = sts per inch not sts in your whole swatch. So presuming you did 18 sts/4" thats 4.5 per inch. Time 18" is 81. That's C. Rounding it down to a multiple of 4 is 80 sts, that's D and what you CO. After you knit the ribbing you're supposed to inc back to the C number, but I don't think 1 st (what E is, the difference between c and d) is going to matter a whole lot. You can add the st if you want, but it's less than a quarter inch.

Thank you soozeq!  I didn't even realize that I measured my swatch wrong to begin with.  Also, I understand what they are saying alot more now that you explained it better to me. (See, I told you I am terrible at math)  Thank you VERY MUCH for you help!
