Help me! I'm stoopid with math!

[blogslut]

I've been watching this series of crochet stitch videos and the instructor always starts out saying something like: "Create a foundation of chain stitches in multiples of 3 + 2." or "multiples of 7 + 5"

I understand multiples of 3 or 7 or 5 or whatever, but it's this plus business. What does it meeeeean?

1. Will this help?

2. Not really.

Ir's this plus business. Plus what? Multiples of 3, I know - 6, 9, 12, 15, 18, blah, blah. But what does the plus two mean?

3. I'm tapped out, I know nothing of stitching or math

But I wanted to try to help. It will take one wiser than me

6. Okay, here's an example video.

The confusing part is near the beginning. He instructs the viewer to create a foundation chain in multiples of 4 + 3:

Is he being literal? Like if I'm aiming for 40 stitches, do I chain 43? 4 x 10 + 3 = 43?

7. I know nothing of crochet

but from a math perspective, I think this either means a multiple of both numbers (ie a multiple of 3 and 2 or a multiple of 7 and 5) or a multiple of 3 (say 9) then add 2 for 11 or a multiple of 7 (say 42) then add 5 for 47.

8. So, he's being literal, you think?

Just add the b number of stitches onto the multiple of a stitches?

9. If he is using the word plus

then I would think my second choice is more likely, if he is using the word and, then the first.

10. Thank you!

11. Go to Ravelry.com to ask.

12. The + are extra stitches at the end of the multiple chain.

Usually they're used to turn the next row.

13. ^^ exactly, extra LOOPS really... not tied into the under row thing there.

Directions always made me cross eyed, no offense to anyone who's cross eyed of course.

15. The plus are extra loops for the next row

Like 'multiples of 7 +3' would mean multiples of 7 (7, 14, 21, etc) plus an extra 3 at the end of the row...extra 3 would be in place of a first double crochet on the next row.

So multiples of 7+3=
7+3=10
14+3=17
21+3=24
28+3=31
35+3=38

Etc etc

The +number is for whatwever stitch on the next row. So if you're starting with a single crochet, it would be +2 (the +2 is your turning chain, and makes the first single crochet of the next row), +3 for double crochet, +4 for half double (I think) and +5 for triple crochet

Think of the +___ as the first stitch of the next row since they're not attached to any stitches from the previous row:

Multiple of 5+3:
