 13-08-2021, 02:50 Addition and Subtraction 140 0 Adding large numbers (that is, multiple digit numbers) follows the same organizational principles as adding single digits. All numerical addition relies on the understanding that the sum does not change depending on the order in which the numbers are added, nor is the value of any number affected by breaking it into its component parts. Employing these simple fundamental principles, you 11-08-2021, 20:10 Mathematics 254 0 In trying to find a formula for some mathematical sequence, a common intermediate step is to find the n term, not as a function of n, but in terms of earlier terms of the sequence. For example, while it'd be nice to have a closed form function for the n term of the Fibonacci sequence, sometimes all you have is the recurrence relation, namely that each term of the Fibonacci sequence is 11-08-2021, 02:20 Volume 401 0 Whether you need to mail a package or pass you next test, finding the volume of a box is easy. Volume is the measure of how big an object is in three dimensions, so the volume of a box measure how much room there is inside of the box. To find it, you need to make a few simple measurements of length, width, and height, and then multiply them. 10-08-2021, 02:00 Fractions 166 0 Fractions are composed of a numerator and denominator, and when two fractions have the same number for a denominator, it is known as a common, or like, denominator. Adding fractions together when they have a common denominator is easy to do, because you can just add all the numerators together! The new fraction will use the same original denominator, so all you have to worry about is 9-08-2021, 21:00 Surface Area 192 0 A prism is a three-dimensional shape with two parallel, congruent bases. In a triangular prism, the bases are triangles. A triangular prism also has three lateral sides. To find the surface area of triangular prism, you first need to find the area of the lateral sides, then you need to find the area of the bases. Finally, you need to add these two areas together to find the total 9-08-2021, 15:40 Calculating Volume and Area 227 0 A rectangle is a plane, a quadrilateral that has 4 right angles. The sides that are parallel to each other are identical in length. If the rectangle has four equal sides, it is called a square. All squares are rectangles, but not all rectangles are squares. The perimeter of an object is the sum of all the lengths of the sides of that object. The area is the product of the length and the 6-08-2021, 20:00 Surviving Mathematics 57 0 Having difficulty concentrating in math class? Maybe you have trouble connecting to the subject and understanding where it fits into real life. For a number of reasons, it might be difficult to concentrate in class, and your grade suffers. From keeping your brain sharp to quick note-taking tips, there are a number of ways you can transform your hopeless math grade. 6-08-2021, 17:10 Probability and Statistics 322 0 P value is a statistical measure that helps scientists determine whether or not their hypotheses are correct. P values are used to determine whether the results of their experiment are within the normal range of values for the events being observed. Usually, if the P value of a data set is below a certain pre-determined amount (like, for instance, 0.05), scientists will reject the "null 4-08-2021, 14:00 Coordinate Geometry 270 0  3-08-2021, 17:40 Conversion Aids 273 0
