In mathematics, we often think of figures in terms of three-dimensional objects instead of two-dimensional objects. In fact, everything around us is three-dimensional. So, let’s make sure that we can calculate the size of three-dimensional objects. In elementary school geometry, we learn formulas to calculate the size of three-dimensional figures. Also, the size of a […]

Sometimes we make a shape bigger or smaller. Although the shape is the same, the size of the figure and the length of the sides are different. There are two types of such figures: enlargement and reduction. When you make a figure larger, it is an enlargement. On the other hand, when a figure is […]

In math, we learn geometry. One of those areas is congruence. When there are two equal shapes, they are congruent shapes. If we understand the concept of congruence, we can understand line and point symmetry. There are many shapes around us that have a line or point symmetry. So, try to understand what shapes are […]

In elementary school math, students are asked to solve problems involving circles. A circle is a figure with a round shape. In a circle shape, you are asked to find the length of the circumference and the area of the circle. In order to do these calculations, we need to use Pi. When learning about […]

In elementary geometry, we learn about quadrilaterals and triangles. We are often asked to find the area of a shape. The area is the size of the shape, and you can find the area of a quadrilateral or triangle by using the formula. On the other hand, if you don’t remember the formula, you won’t […]

Triangles and quadrilaterals are the most common shapes used in plane figure problems. If you don’t understand the properties of triangles and quadrilaterals, you won’t be able to solve elementary school math problems involving shapes. In particular, angles are important in geometry problems, so learn the angles of triangles and quadrilaterals. There are different types […]

In elementary math, we learn about shapes. An important part of shapes is an angle, and the shape changes depending on the angle. Among the angles, a special angle is a right angle. If the angle is 90 degrees, it is called a right angle. After learning about right angles, we also need to learn […]

Fractions and decimals are two ways to express numbers less than one. Both are frequently used in math calculation problems. The important thing to remember is that fractions can be converted to decimals. Decimals can also be converted to fractions. So, it is important to understand how to calculate them. Also, in math, you should […]

When dividing fractions, there is a right way to do it. First of all, you do not do division with fractions. To be more precise, all dividing fractions need to be converted to multiplying fractions. In other words, in order to do the division of fractions, you need to understand how to convert them into […]

We learn about fractions in elementary school math. When we calculate fractions, we use multiplication. Multiplication of fractions is easier than addition and subtraction. This is because we don’t need to make the denominators the same by finding the common denominator. However, when multiplying, we need to simplify the fractions. Also, when multiplying fractions, it […]
