Fractions..this is an elementary question... 3- 10/3?

We Answered:

first u havta make them both have a common denominator and since 1 is common to 3, you can make 3 equal to 9/3. then u just do 9/3-10/3 which is -1/3.

sry if this is confusing .hope i helped

Elementary math and reducing fractions?

We Answered:

haha well some numbers are prime and other numbers do not share common factors, ie cannot be reduced

welcome to math!

try 3/9, 3/3 = 1, and 9/3 = 3, so that gives you 1/3

4/9 - you cannot do because 4 = 2x2 and not 3. nine not divisible by 2

get it?

Help with easy elementary math! What are some fraction tips and methods(dividing and multiplying fractions)?

We Answered:

lol at your screen name or display name whatever. haha

Anyway, remember that when you have a fraction, just do the division to get the percentage. When you have a percentage...you can do this

40% off a $100 video game (eesh!) goes like this:
.40 * 100 =$40 off the video game
$60 = game with 40% off

What are four elementary functions that do not have elementary functions as antiderivatives?

We Answered:

?Explanation?

Some examples are:

ln(ln(x))
e^(-x/2)
?(1 + x^4)
1/ln(x)

You can't integrate elliptical derivatives, diverging functions, logarithmic and exponential derivatives.

What's a good book to learn fractions, percentages and elementary algebra?

We Answered:

I really like the web-based program Aleks. The cost is reasonable (about $20 per month, cancel anytime), no textbook is necessary (the program includes the explanations). You choose your course. (I suggest prealgebra first and then algebra, you can change coursed at any time without any change in the cost.) Aleks will assess where you have learning gaps, assign you topics to learn, and continue to assess your progress. Each course includes assements and learning of topics of previous courses, since math builds on itself, and previous learning gaps are a significant source of difficulty for students. There is immediate feedback and comprehensive reporting of your progress. It works like your own math prep course, designed specifically for your needs. There is a free trial available, so you can see if it feels like something that might work for you. I have used it with my students and it has been very successful for them.
