What Is the Best Way For Me To Understand the Math Topics I get Wrong

Test Preparation SAT Preparation
1

<p>I took two math sections from a test in the BB, and the following are the types of questions wrong:</p>

<p>Arithmetic-Number Lines</p>

<p>Coordinate Geometry- Lines (Slope)</p>

<p>Geometry- Right Triangles</p>

<p>Geometry- Solids</p>

<p>Geometry- Circles</p>

<p>Arithmetic- Percents</p>

<p>Probability</p>

<p>Geometry- Equilateral triangles</p>

<p>How can I read up on this material, and learn everything I need to know on the questions I'm getting wrong? Is there a guide or a certain book that you recommend that will enable me to learn this stuff?</p>

<p>I am learning how to do the question, but I want something that will tell me everything about that certain topic. For example, circles, or triangles.</p>

<p>Please help! I'm still stuck in the 600 range.</p>

<p>I understand geometry through algebra, and arithmetic through language.</p>

<p>Probability - is for rocket scientists to understand. But once you master permutation and combinations, and understand the very tricky way in which they frame questions, you can at least solve the problems. But the good thing is, probability problems on the SAT are very basic.Doubt you’ll even need PnC.</p>

<p>So for example, for percents, there was this neat translation tip somewhere.</p>

<p>What percent of 90 is 15? translates to x/100 * 90 = 15</p>

<p>of -> *
what -> x
percent -> /100
is -> =</p>

<p>For number, picture a standard 6" ruler. There’s really nothing else to it. And always translate the question into real-people-speak. They just try to freak you out. Mark the dots. When they say bisect actually halve the thing. Then replace bisect with the halved number (or even x/2) when you read it. As you solve, replace words in the qs with info you’ve gathered.</p>

<p>Slopes, all you need to know is in y=mx+c, m is the slope and c is the y-intercept. Whenever y has a number multiplying it, the slope becomes m/number. AND, when you put y=0, you get the x intercept, which is basically -c/m. So you can picture the entire line. It’s again a ruler. Pointing down - neg slope. Which basically means that for every change in x, y is decreasing.</p>

<p>For triangles, all you should remember till you can’t feel it any more, is the pythagorean theorem. This’ll not just do for all kinds of triangles, but also for most quadilaterals. When in doubt, drop a perpendicular and do that thing.</p>

<p>I know it’s all easier said than done but I feel that the difference between a 600 and an 800 in Math on the SAT (unlike on CR and W in which aptitude actually comes to play along with practice) is, as I said, practice. And the most helpful math tip I’ve come across is - every SAT I math question can be solved in less than 30 seconds. Whenever I feel overwhelmed, I remember that and realize it’s just freaking me out for no reason. There’s a trick, and if you think it’s hard you’re overdoing it. (Sometimes self-help methods really work.)</p>

<p>Oh, and I think Khan academy will teach you the concepts fantastically well.</p>
