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 […]

Addition and Subtraction: Arithmetic of Carrying and Borrowing

In elementary school mathematics, we learn addition and subtraction. When studying addition and subtraction, a difficult calculation is carrying. 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 10, you will be able to calculate carry […]

Inscribed Angle Theorem: 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 are properties of inscribed angles, which is called the inscribed angle theorem. If you do not understand the theorem, you […]

Pythagorean Theorem: Formulas and Calculation Methods

One of the things we learn in mathematics is the Pythagorean theorem. Even if there is a side with an unknown length, you can use the Pythagorean theorem to calculate its length. In order to understand the Pythagorean theorem, you need to have already learned about square roots. As long as you understand square roots, […]
