In mathematics, we may calculate the length of the arc and area of a sector. How do we calculate the arc length and the sector area? When calculating the arc length and the sector area, we must understand the properties of a circle. If we can calculate the length of the circumference and the area […]
In mathematics, we study probability. Probability is so familiar in our lives and all statistics are based on probability. It is because we study probability that we can understand what the news is about. Also, experimental data in science is processed using probabilities. Whether or not it will rain in a weather forecast is also […]
In mathematics, we learn about quadratic functions. It is a quadratic function with a graph of squares, and the graph has a curve. In mathematics involving graphs, we first learn direct proportionality. A graph that makes an application of proportional is a linear function. Further development of linear functions is quadratic functions. Linear and quadratic […]
An area that must be learned in mathematics is quadratic equations. Compared to linear equations, quadratic equations are more complex to calculate. In quadratic equations, there are multiple ways to answer the question. Square roots, factorization, and quadratic formulas are the most common ways to solve quadratic equations. When solving a quadratic equation, we must […]
An area of study in mathematics is square roots. The square root allows us to represent numbers before they are squared. Square root calculations include addition and subtraction. For multiplication and division, we can just multiply the numbers in the root symbol as they are. For addition and subtraction, on the other hand, the rule […]
Fractions are frequently used in square root calculations. In the calculation of fractions, the denominator may contain the root symbol. In that case, if the root sign is still in the denominator, the answer is wrong. When calculating the square root, if the denominator contains the radical symbol, it should be removed. This process is […]
In the square root, we learn multiplication and division. Typically, in mathematics, we learn addition and subtraction first. But for square roots, multiplication and division are easier. We can just multiply the numbers in the root symbol. However, there are rules for multiplication of square roots. And few people understand why it is okay to […]
An important area of study in mathematics is square roots. In mathematics, we calculate powers; we multiply numbers by squaring or cubing them. Square roots are the relatives of powers. If you have learned the concept of powers, you can understand square roots. Square roots also use a symbol called root symbol (or radical symbol). […]
After learning the definitions and concepts of proportional and inversely proportional in mathematics, the next step to study is linear functions. Similar to the graph of direct proportionality, it is linear functions that if the value of $x$ increases, the value of $y$ increases in the same ratio. In linear functions, there are two concepts: […]
In mathematics, we may use two equations to solve a calculation problem. If there are two unknown numbers in the equation, we cannot find the answer. However, if there are two equations, we can find the answer even if there are two unknown numbers in the equation. A combination of two or more equations is […]
