? SAT Math Test: Algebra Algebra: Many algebraic problems in the redesigned SAT depend on the direct application of the skills you learned in high school math class-for example, solving X. The more difficult task is to understand when and how to use these algebraic skills. For example, consider this example problem involving three equations. Students who have confidence in their algebra skills may immediately start to simplify terms. However, a strong SAT candidate will realize that the equations enjoy solutions at the points where they intersect. The whole problem can be solved by finding the intersection of equations. The answer is B-you don't need math to solve it. Hone these skills by becoming as familiar with these charts as possible. As the variety of charts you see increases, you will eventually be able to identify patterns more quickly and find the path to the answer quickly, for example, in this case.
? SAT Math Test: Geometry Geometry: Like algebra, the key to geometry test is to know when to apply the appropriate formula and which other basic rules may be relevant. This challenging sample geometry problem depends on the examinee's application of Pythagorean theorem to recall the characteristics of the circle. To find the distance x between two lines, draw a line from the center of the circle to point d and create a line with sides of r, x and? R's right triangle. Substitute these values into Pythagorean theorem-(? R) 2+x 2 = r 2–Solve x and you have the answer. A simple understanding and familiarity with Pythagorean theorem will help you in many geometric cases. When you find an opportunity of a right triangle, immediately consider whether Pythagorean theorem can help you identify the missing information that can bring you the correct answer. Geometry is everywhere in the real world, from hanging pictures on bent wires to understanding why larger tires on cars affect speedometers. It is very important to master how objects are related to each other in space.
? SAT math exam: data analysis data analysis: some data analysis items in the redesigned SAT are also chart or graphic analysis questions. Consider this sample set consisting of three questions. At first glance, the initial problem seems to be a biological problem. However, you can use any other words instead of anatomical terms, and you can still solve this problem easily. What you need to know is that by finding the difference of a point, you can calculate the number of units that separate the point from the line on the Y axis; The chart data displayed as the X axis leads to the Y axis-that is, Y depends on X; By finding the y value corresponding to a specific x value, the best fitting line can be used to predict the data. The answer here is B. Data analysis is ubiquitous in the post-SAT era. For example, understanding a temperature chart by date requires you to find the connection between a certain time of the year and the average high or low temperature. For example, it may be useful to understand such a chart when you are trying to decide which university campus on a candidate list has the warmest weather, or when you are considering moving to a new city.
? SAT Math Test: Story Question Story Question: The last major challenge of the redesigned SAT is to decode the story question. As this story question shows, not every question contains a given equation. Knowing how to translate words into equations is the main part of the test. What does "doubles" mean in this question? How to express the concept of "with time" in mathematical equations? A good first step is to simply assign variables to these concepts-substitute them into an equation, and then you can find the answer. If you haven't guessed, the answer is D. Knowing how to translate words into mathematical equations can provide you with a good service outside the SAT. Take the waiter in the restaurant as an example. They may be asked to divide the cost of appetizers among two diners, but divide the remaining bill among five people.
