Set goals and desires, pursue success academically and in other areas, cultivate a sense of self-worth and image, and make sure you develop positive relationships.

Swipoa or better known as "abacus" (with suanpan or Chinese swipoa as the most helpful model) is a simple calculation tool that is still used throughout the world. It is a useful study tool for those with visual impairments, as well as anyone who wants to learn about the origins of the modern calculator.

The Greatest Common Divisor (PTS) of two integers, also called the Greatest Common Factor (GCF), is the largest integer that is the divisor (factor) of both numbers. For example, the largest number that can divide both 20 and 16 is 4. (Both 16 and 20 have greater factors, but no greater equal factor – for example, 8 is a factor of 16, but not a factor of 20.

Many people study math like studying for a history exam. They only remember formulas and equations like memorizing facts and historical years. While it's important to know formulas and equations, the best way to learn them is to use them. This is one of the advantages of math, you can just do it.

This article teaches you how to calculate the average standard error using Excel. Calculate the standard error by dividing the Standard Deviation (σ) by the square root (√) of the number of samples. Step Step 1. Open Microsoft Excel The app has a green icon that looks like a spreadsheet with an “X” on it.

The binary (base two) numeric system has two possible values, either 0 or 1, for each place value. In contrast, the decimal (base ten) numeric system has ten possible values (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) for each place value. To avoid confusion when using different numeric systems, the base of each number can be subscripted.

A basic part of learning algebra is learning how to find the inverse of a function, or f(x). The inverse of a function is represented by f^-1(x), and the inverse is usually represented visually as the initial function reflected by the line y=x.

Subtracting fractions from integers is not as difficult as it seems. There are two main ways to do this: you can convert an integer to a fraction, or you can subtract 1 from the whole number and turn 1 into a fraction with the same base as the subtracting fraction.

The circumference of a circle is the distance around its edges. If a circle has a circumference of 3.2 kilometers, you will have to walk 3.2 kilometers around the circle before you finally return to where you started. However, when you do math problems, you don't have to leave your seat.

The decimal (base ten) number system has ten possible values (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) for each number position. In contrast, the binary (base two) number system has only two possible values represented by 0 and 1 for each number position.

Have you ever left a bottle of water in the hot sun for a few hours and heard a slight "hissing" sound when you opened it? This is due to a principle called vapor pressure. In chemistry, vapor pressure is the pressure exerted by the walls of a closed container when the chemical substance in it evaporates (turns into a gas).

A bar graph, also known as a bar graph, is a graph that uses rectangular bars to display different values to show a comparison between categories, such as the amount of rainfall that occurs during several months of the year, or the average salary in different cities.

A mathematical function (usually written as f(x)) can be thought of as a formula that will return the value of y if you enter a value for x. The inverse of the function f(x) (which is written as f -1 (x)) is actually the opposite: enter your y-value and you'll get your initial x-value.

Scientific research often relies on surveys distributed to a specific sample of the population. If you want the sample to represent the population condition accurately, determine the appropriate number of samples. To calculate the required number of samples, you must define some numbers and enter them into the appropriate formula.

Determining whether three side lengths can form a triangle is easier than it seems. All you have to do is use the Triangle Inequality Theorem, which states that the sum of the two side lengths of a triangle is always greater than the third side.

In mathematics, the concept of percent change is used to describe the relationship between the old value and the new value. More specifically, the percentage change represents the difference between the old and new percentages as a percentage of the old value.

The square root of a number is easy to find if the answer is an integer. If the answer is not an integer, there is a series of processes you can follow to get the square root, even if you don't use a calculator. For that you need to understand the basics of multiplication, addition, and division.

An equilateral triangle has three sides that are the same length, connected by three angles that are equal in width. Drawing an equilateral triangle by hand is a challenge in itself. However, you can use a circle object to mark the corners. Make sure you use a ruler to make straight lines!

To find the area of a semicircle, find the area of the full circle, then divide by two. See Step 1 for a quick way to find the area of a semicircle. Step Step 1. Find the radius of the semicircle The value of the radius is needed to find the area of a semicircle.

Pi (π) is one of the most important and interesting numbers in mathematics. Around 3.14, pi is a constant used to calculate the circumference of a circle from the radius or diameter of the circle. Pi is also an irrational number, which means that pi can be counted to infinity of decimal places without repeating the pattern.

The inch is the standard unit of length in the imperial system of measurement. If you're trying to measure in inches, it's best to use a tool specifically designed for measuring inches. Fortunately, even if you don't have a tool of this type, there are ways to estimate and/or convert other units of measurement to inches.
