Basic Operations Example

In mathematics, Basic operations Are the expressions for how numbers affect each other, obtaining a new number as a result of this. These operations accompany most of the activities of daily life, such as the purchase account, the distribution of money between expenses, the discount on a merchandise.

To indicate that a number is being modified or affected by another (s), the Math signs. These will tell us what operation is involved among the four main ones: Addition, Subtraction, Multiplication and Division.

Sum

The Sum, also called Addition, is the basic operation in which the numbers add to each other, accumulating to have a result.

To indicate it, the sign "+" is used, which means "plus". It is placed between the numbers to be added. And to indicate the result, after the last number the sign "=" is put, which means "equal to ...".

Each of the numbers in the Sum will be called Terms of Service.

Sum example:

2 + 5 = 7

2 "more" 5 "equal to ..." 7

Subtraction

La Resta, also called Subtraction, is the basic operation in which the numbers 

they counteract each other, having a positive or negative result, defined by the number with the highest value.

To indicate it, the sign "-" is used, which means "minus", which is placed between the numbers that are going to participate in the subtraction. And for the result, after the last number the sign "=" is put, which means "equal to ...".

The main number is called Minuend, and the one who exercises the subtraction is called Subtracting.

Subtraction Example:

10 – 3 = 7

10 "less" 3 "equal to ..." 7

Multiplication

Multiplication is the basic operation in which a number adds to itself repeatedly. That "number of times" will be the second number. You will have a result whose value will not matter if you put one number first or the other.

To indicate it, the signs "x" or "*" which mean "by" or "times" are used. And for the result, after the last number the sign "=" is put, which means "equal to ...".

Each of the numbers in the Multiplication will be called Factors.

"The order of the factors does not alter the product".

Multiplication Example:

4 * 5 = 20

4 "times" 5 "equal to ..." 20

Division

Division is the basic operation in which a number is to be divide yourself into several parts, defined by a second number. It will have a result smaller than the initial number.

To indicate it, the sign "/" is used, which means "between" or "divided by". And for the result, after the last number the sign "=" is put, which means "equal to ...".

The main number is called Dividend, and the second, which exercises the division, is called Divider.

Division Example:

8 / 4 = 2

8 "between" 4 "equal to ..." 2

Examples of Basic Operations

Examples of Sum:

10 + 6 = 16

1 + 8 = 9

2 + 12 = 14

50 + 20 = 70

19 + 4 = 23

5 + 12 = 17

4 + 19 = 23

30 + 5 = 35

90 + 20 = 110

15 + 3 = 18

Examples of Subtraction:

10 - 6 = 4

1 - 8 = -7

2 - 12 = -10

50 - 20 = 30

19 - 4 = 15

5 - 12 = -7

4 - 19 = -15

30 - 5 = 25

90 - 20 = 70

15 - 3 = 12

Examples of Multiplication:

10 * 6 = 60

1 * 8 = 8

2 * 12 = 24

50 * 20 = 1000

19 * 4 = 76

5 * 12 = 60

4 * 19 = 76

30 * 5 = 150

90 * 20 = 1800

15 * 3 = 45

Examples of Division:

10 / 6 = 1.6667

1 / 8 = 0.125

2 / 12 = 0.1667

50 / 20 = 2.5

19 / 4 = 4.75

5 / 12 = 0.4167

4 / 19 = 0.2105

30 / 5 = 6

90 / 20 = 4.5

15 / 3 = 5
