yes you do. things like calculas but it depends on how good you are in math.
No. Pre-algbrea is for kids who need to go deeper then one-time notes. Intergrated algebra is like an advance math class.
Most Universities require the SAT and the highest math that the SAT goes up to is algebra 2, so if you want to do well on the SAT and get a good score in the math section you will need to take an Algebra 2 course.
I think it is harder than math. You usually need to get straight A's on math to get into pre algebra
Algebra and calculus
In reality you need to know your basics before you can actually start on algebra and yes algebra can help you in basic math when in comes to solving certain word problems
because science is not possible without math..
Strong arithmetic and algebra skills.
Typically a college algebra.
You mean, in high school, to prepare for college? The courses taught in high school will probably vary from one country to another, and from one college to another, but typically include algebra, geometry, trigonometry (which might be included in algebra), and perhaps a few others, such as a second algebra course. You don't really need any of these for college, unless you study some sort of engineering in college. In college itself, if you DO study engineering, you'll need several advanced math subjects.
i think quite alot because you need to do math and stuff.
You need to explain your question in more detail.
Most colleges require 1 class each of Chemistry and Algebra. My nursing school also included Nursing Math in their program that teaches medication doses and figuring IV drip rates. Hope this helps
