Here are short articles answering one specific question.
Definition. In simple terms, a fraction is a part of something. This "something" can be anything - food, money, a number. The word "fraction" also speaks for itself - it means a division.
Let's look at an example from life. We bought a pizza to eat during the day. Let's say we decide to divide it into four pieces so that we eat one piece at a time.
Look at this picture. Imagine that this is our pizza divided into four slices. Each slice of pizza is a fraction, because each slice individually is part of the pizza.
Let's say we ate one slice. How do we write it down? First a little line is drawn:
The bottom of this line records how many slices the pizza was divided into. The pizza was divided into four slices. So at the bottom of the line you write four:
Definition. If any number is divisible by another number without a remainder, it is a multiple of that number.
For example, 6 without a remainder is divisible by 3. Therefore, 6 is a multiple of 3.
6 : 3 = 2
Definition. A multiple of a is a number that is divisible without a remainder by a.
Definition. The plus sign symbol (+), indicates addition and is used when combining two values.
The result from bringing them together is called the sum.
For example, 3 is added to 2.
Write 3 + 2 = 5
In this example, 3 is the summand, 2 is the second summand, and 5 is the result sum.
In the future we will have to add quite large numbers. But combining this big numbers will eventually come down to combining small numbers.
Division
Definition. It is signified by the division sign (÷ or : ) and is used when dividing numbers. The division is a method of distributing a group of things into equal parts.
the number that is being divided in the division process is called a dividend.
The number by which dividend is being divided by is called divisor.
The result obtained in the division process is aquotient.
Definition. Division is the action of dividing something. Division consists of three parameters: the divisor, the divisor and the quotient. The divisible is what is being divided. The divisor is a number that shows how many parts to divide the divisible. The quotient is the actual result.
For example, suppose we have four apples:
Divide them equally among the two friends. Then the division will show how many apples each will get. It is easy to see that everyone will get two apples:
Inequalities (Relation operations)
The word "relation" speaks for itself.
Lets start with an example: Object A is related to Object B. Dad has a relation to Mom. This relation is called a marriage:
Examples of relationships abound.
We can say that our beautiful world, which develops harmoniously, also consists of relationships.
Multiplication
Definition. Multiplication is signified by the multiplication sign (×) and is used when one number is multiplied by another. The word multiplication speaks for itself - some number is multiplied by a certain number of times, i.e. multiplied.
For example, writing 4 × 3 means that a four will be multiplied by a factor of three during the multiplication operation.
the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier. The result of a multiplication operation is called a product.
Multiplication is when you take one number and add it together a number of times.
Definition. Place value is the value of each digit in a number, every digit in a number has a place value.
Take the number 635 as an example.
This number consists of three digits: 6, 3 and 5.
The digits should be read from right to left. In the number 635, the first position has digit 5, the second position has digit 3, and the third position has digit 6.
The position where the number 5 is located represents ones
The position where the digit 3 is located represents tens
The position where the number 6 is located represents hundreds
Subtraction
Definition. The subtraction is signified by the minus sign (-) and is used when taking one number away from another.
For example, subtract 2 from 10.
10 − 2 = 8
In this example, number 10 is the diminishing number, number 2 is the subtracting number, and number 8 is the difference.
