somethign my 3ed grade teacher tought me.. it;s u know the largis number ..liek u said 8+ 7...well u say 8 and then wiht ur fingers u count.. 9 1o 11 12 13 14 15 (hold up 7 fingers) each finger is a numer up. cuz that;s wut ut doing is adding a number up. by 8th grade i can do smal numbers in my head. .liek say 9+3. the 3 is a small number so i can think 9, 10, 11, 12.......but when it gets bigger than a 5 i have to go to my fingers. lol

]]>Anyways, I hope you find a way to get through your math problem :T. I wish you the best for your math clas :laughing:

]]>well... I don't know if it means anything but things like 8+7, when i do it, I just think 8+2 is 10 and what's left over of seven is 5 so the answer has to be 15That's exactly what I do. And I have to do "simple math" like that every day.At my job (Subway), I'm the one who has to make more bread in the afternoon. First I have to count how much we have of each bread (easy) then I have to figure out how much more we need. Well we're supposed to ahve 60 white, 45 wheat, 24 herb and cheese, 16 monterey cheddar, and 12 honey oat.Now after I count the bread, it may look something like: 27 white, 16 wheat, 14 herb and cheese, 7 cheddar, and 9 honey oat.In this case, here's how I would figure it out:White: We have 27, need 60. I would simply add 3 to 27 to get 30, then add 30 since 30 is half of 60. So we need 33 white.Wheat: Have 16, need 45. I would subtract 6 from 45 to get 39, then subtract 10 more to get 29. We need 29 more wheat.Herb and Cheese: Have 14, need 24. Easy, 10.Cheddar: Have 7, need 16. Subtract 6 from 16, then subtract 1 more. We need 9.Honey Oat: Subtract 2 from 12, then one more. We need 3.

]]>But what you'd do is try to do one in 5 minutes. If you get all the answers correctly, do the next one in 5 minutes and try to get all of them right. If you don't get all of them right or don't finish in the 5 minutes, do it again the next day. This is the order it's better to do them in: +,-,x,รท. Once you get through division, shorten your time by 30 seconds.

This is what we did in 5th grade, and rote memorization is probably the best way for this simple math.

I don't know what a good time to shoot for is because I've always been really advanced in math (Calc 2 and 3 as a Junior, college level Calc 2 and 3, not watered down...) so I got to 1:30\. I'd say a good time is 2:30 or 3:00, but I'm not sure.

Hope this helps. ]]>
