If you guys have anything, anything at all let me know cause all i want for her is the best and to have a good education. THANK YOU ALL!!
For a bachelors degree how good do you have to be at math? A list of math courses would be good. No designating math sequence course #s because; I won’t understand what they what they mean. Each college/university has their own standards. Rather just provide the names to the math courses. Easy ten points.
My youngest has a math teacher who is telling him that he can make a C in art, English, science, history, or anything else because none of those subjects matter as much as math for the future. I’d like to see my son make higher grades in math, but somehow this method doesn’t seem a positive or helpful one. I’ve talked to this teacher, and he is adamant that math is more important than any other subject, and the principal doesn’t have a backbone. Ideas?
as long as its over like a 4th grade level im 17 and i could use any and all math tips tricks plz lol. (i suck at math).
I’m thinking of majoring in either economics or marketing. I took economics my senior year of high school, and I really enjoyed it. But I wanted to know how much math is involved. I’m good at basic maths and algebra, but it gets a little sketchy after that. I’ve heard from people that not much hard math is required, but I’ve also heard that math is something you’ll use a lot in college if you’re a business major.
The inhabitants of the planet use six coins in their currency system: the Barj, the Berj, the Birj, Borj, the Burj, and the Byrj. A borj is worth 8 1/2 Berjes, a Birj is the equivalent of 1/6 of a Barj. Abyrj is worth a Birj less than a Burj, but is also worth a Berj more than a Borj. the mean of a values of the Borj and Burj is 1/3 of a Birj less than the value of a Byrj. A Barj is worth less than a Borj, but more than a Berj. order the six coins from greatest to least value.

I am going to be a Pre-Law major, but I wanted to choose a math friendly minor for marketing purposes. Also, I want the option of going into corporate law, and I will need math skills for that. On that note, I feel it would be in my best interest to minor in economics. I just wanted to know how intense and advanced the math would get. I’m an average math student.
You know the ones where you multiply, divide, add, and subtract and at the end you get a number thats always going to be that number?
I recently learned about a trick that allows me to multiply numbers 11 – 19 completely mentally. It is fantastic. So much so that I was wondering if there were any other great tricks like that one that I can use to progress in math. My math grades are good, so that’s not the issue, but any mental math tips would be welcomed.
Can someone help me with this??? Thanks
Solve each equations. First, undo the addition or the subtraction. Then undo the multiplication or division. Type you answers in the spaces provided.
1. 3w – 5 =16
2. 3x + 2=8
3. u (Over) 3 + 9=18
4. 11v + 8=19
5. 4a + 7=19
6. z (Over) 7 – 1= 3
7. 4m – 6 = 10
8. e (Over) 4 +15 = 16
9. y (Over) 5 – 3 = 2
10. s (Over) 3 -5 = 3

AIME, USAMO, AMC, and ARML.
I’ve always been alright at math, taking Academic level classes in high school and completing up to Alg. II. My question is: Since my college path requires me to take up to Calc I, will I be alright at it? How difficult will it be for a so-so math student?
Slove for the equation for y
