Arithmetic Concepts
Arithmetic deals with numbers and the basic operations used on them. The operations are called addition, subtraction, multiplication, and division.
Each of these operations is a building block for more complex math concepts and is used in everyday life.
Addition is the process of combining two or more numbers to get a total sum. When you add, you start with one number and increase it by the value of another number. For example, if you add 3 and 2, you get 5. Addition is often represented by the plus sign (+).
Subtraction is the process of taking one number away from another. It’s used to find out how much is left when a certain amount is removed from a larger amount. For example, if you subtract 2 from 5, you are left with 3. Subtraction is represented by the minus sign (−).
Multiplication is a way to add a number to itself a certain number of times. For instance, if you multiply 3 by 2, you are essentially adding 3 two times (3 + 3), which equals 6. Multiplication is represented by the multiplication sign (×) or sometimes by a dot (·).
Division is the process of splitting a number into equal parts. It tells us how many times one number is contained within another. For example, if you divide 6 by 2, you are splitting 6 into 2 equal parts, each of which is 3. Division is represented by the division sign (÷) or a slash (/).
Fractions are a way to represent parts of a whole. They are composed of a numerator (the top number) and a denominator (the bottom number). Fractions are used in many areas of everyday life, such as measuring ingredients for a recipe or dividing a pizza into equal slices.
Understanding fractions is essential for grasping more complex mathematical concepts, such as ratios, proportions, and percentages.
