Hmm, I might look into that, that totally describes me!

Seriously, it's so bad that shortly after I graduated from high school, I had considered going to the police academy to become a police officer...I was doing some research on it and saw that it was very helpful to have a background in criminal justice before attending the police academy...So, I went to my community college to speak with a counselor about a CJ program and find out what classes I would need to take, and, possibly take the entrance exam. Well, when I was informed there would be math involved with the entrance exam and I would most likely have to take some gen ed math classes, well, I didn't take the entrance exam and never went to college....hahahaha....Yeah, my fear of math is so bad I skipped out on going college

LOL! Silly girls, calculators are wonderful lil things!

My eighth grade algebra teacher passed me just out of pure pity!

I'm tellin ya, working/managing a sewing plant, samplemaking of totebags, aprons and boxer shorts was my algebra teacher. Having to make sure that production stayed up was a big help when it came to time studies.

Time studies is the detail you need to know when you're pricing a job with multiple quantities. I would time each operator as she did her part of the manufactured item during the time study. Adding all the times together would tell me how many minutes each operation took so that I could make a profit. Money was the motivation for learning the math. So if Jane could hem 125 pieces per hour, 125 divided by 60 would tell me how much time to add to the quote, plus all the other operations. Totebags, in production are only worth around \$3.49...that's for a large size. Fabric, needles, downtime, thread and all overhead has to be figured in as well. When someone mentions that time is money, this is what they mean.

This is the detail needed to price anything. I'm really glad I don't have to knit in production like the ladies in China!

Me: (thinks and decides not to say no) Ummm... It's Groundhog Day.. Teacher: This has nothing to do with algebra so I suggest you face forward and listen! Me: okay That sums up my math career... I have learned how to do a lot of things in my own way and I can usually do pretty well even with knitting math. My biggest problem even with calculators is other than basic stuff, I don't know which numbers to put in first or what function to use to get the answer. So someone telling me to use a calculator does no good unless I know what I'm doing. Kind of like telling a kid to look up pneumonia in the dictionary if they have no clue whether it begins with a P, an N, or an F. __________________ Jan When asking questions ALWAYS post the name and a link for the pattern if you have it.

I've been making soap for over 10 years and just started knitting. The math in both are my worst hurdles. I made a chart to follow whenever I formulate a soap recipe but knitting is a whole new animal. I read the past thread about gauge and my eyes crossed, my brain went dead and ...

You are not alone
I graduated with a dual degree in CJ but had to attend learning disability class in order to get a math waiver after all of that stress, I found out that the waiver has no weight when it comes to taking the entrance exam, nor could it get me into a univeristy so I'm with two degress and no way to get hired. I feel what a waste.

Problems in knitting; how to re-size a pattern. Oh, and that gauge thing too.

Peace and Love,
Joann

This IS the biggest hurdle! Trial and error is a great teacher. Taking it one step at a time helps and getting your brain to put the sequences in order is the key....sometimes the sequences are confusing!
