## Factors and Multiples: Greatest Common Factor and the Least Common Multiple

In elementary school arithmetic, we learn factors (or divisors) and multiples. In our daily lives, we use factors and multiples frequently. So, it is important to understand what they are. In both cases, we use multiplication and division to solve problems. Although the concept is different, we use similar methods to solve the problems. In […]

## Division of Decimals: Quotient and Remainder Calculations and Long Division

Decimals are taught in elementary school mathematics. After learning multiplication with decimals, you need to be able to do division. When calculating decimals, a division is a bit more complicated. This is because it is not always divisible. You have to calculate until you can divide, or use the remainder to get the answer. It […]

## Multiplication of Decimals: Decimal Point Position and How to Solve Problems

In elementary school, students learn decimals in arithmetic. Since multiplication is a common problem in decimals, you need to be able to multiply. Multiplication of decimals is the same as doing long multiplication. You need to pay attention to the position of the decimal point, but other than the fact that there is a decimal […]

## Adding and Subtracting Decimals: How to Calculate in Arithmetic

In elementary school arithmetic, students learn how to calculate decimals, including numbers smaller than one. We use decimals frequently in our daily lives. First, let’s understand what decimals are. By learning how decimals work, we can understand when to use them. Also, we need to be able to add and subtract decimals. Addition and subtraction […]

## Rounding Numbers: Elementary Arithmetic with Approximate Numbers

Instead of using exact numbers, we often use rough numbers. It is called approximate numbers, and we often use rough numbers in our daily lives. A concept that is used in rough numbers is rounding. By rounding off a number, we use a rough number. Why do we need to use rough numbers instead of […]

## Order of Operations: The Rules of the Four Arithmetic Operations in Elementary Math

There are rules when doing math in elementary school. You cannot do the calculations any way you like. There are rules for calculations, and you have to follow the order of the rules. In elementary arithmetic, what are the rules when doing calculations? One of the most important rules is that multiplication and division should […]

## Division and Remainders: Long Division in Elementary Math

After learning multiplication, we will study integer division in elementary school arithmetic. 1, 2, 3, etc., are integers, and we use these numbers to do calculations. The meaning of division is the same as multiplication. In other words, if you can’t do multiplication, you can’t do division. Understand that division is an advanced problem of […]

## Multiplication of Integers: Long Multiplication in Elementary Arithmetic

In elementary school arithmetic, students learn multiplication. Multiplication is used frequently in our daily lives. If you can’t do multiplication, you can’t calculate money when shopping. Therefore, it is necessary to be able to do multiplication. So how can we do multiplication? First of all, you need to understand the meaning of multiplication. Also, you […]

## Addition and Subtraction: Arithmetic of Carrying and Borrowing

In elementary school mathematics, students learn addition and subtraction. When studying addition and subtraction, a difficult calculation is carrying. They don’t know how to do the calculations. Similarly, in subtraction, many elementary school students have difficulty understanding the calculation of borrowing. When adding or subtracting integers, an important number is 10. By finding the number […]

## Inscribed Angle Theorem: Relationship of Central Angle and Arc Length

One of the areas studied in mathematics is the inscribed angle. An angle using a circle is an inscribed angle, and by using the properties of the inscribed angle, we can calculate the angle. There is a property of the inscribed angle, which is called the inscribed angle theorem. If you do not understand the […]
