Notes on Basic Math

Introduction to Notes on Basic Math

In mathematics all calculations made with the basic math operation. The notes on basic math operation names are addition, subtraction, division, multiplication. These functions are mainly used in math and computer. The basic math helps us to find out the result in accurate manner. Here we will see about these four methods notes.

Addition and Subtraction


The notes of addition and subtraction is as follows.

Addition

Addition is used to adding the numbers. We use the symbol +. The other name is sum, plus, increment, total.

Examples

1) Adding the following two numbers. 20, 30.

Solution

The first number is 20

The second number is 30

So add the two numbers= 20

30 (+)

50

2) What is the total of the following numbers? 120, 30, 170, 40?

Solution

The given numbers are 120, 30, 170, and 40.

Total = 120

30 (+)

170

40

360

Subtraction

It is used to find the difference between two numbers. The symbol is -. The other words is minus, less, Decrease.

Examples

1) What is the difference between the following two numbers? 41, 36.

Solution

The given numbers are 41, 36.

The difference between the two numbers is = 41

36 (-)

5

2) Find out the difference between the following numbers? 46, 57.

Solution

Given numbers are 46 and 57.

The difference is 46

57 (-)

-11

The answer is -11. Because the 1st number 46 is less than 2nd number 57. So the symbol must be put which the number is big. I have recently faced lot of problem while learning Quadratic Equation Formulas, But thank to online resources of math which helped me to learn myself easily on net.


Multiplication and Division


The notes about multiplication and division is as follws.

Multiplication

It is used to product the numbers. the symbol is x. the other name is multiplication, multiply.

Examples

1) Multiply the following numbers. 12, 4.

Solution

The given numbers are 12 and 4.

The multiplication is 12 x 4= 48.

2) What is the multiplication of the following numbers? 13, 2, 6.

Solution

Given numbers are 13, 2 and 6.

The multiplication is 13 x 2 x 6 =13 x 12=156.

Division

It is one of the basic math operations. The symbol is ÷. The other name is division, quosient.This is one of the basic math operation.

Examples

1) Divide the following numbers. 12/4

Solution

The given number is 12. The divisor is 4.

The division is 12/4=3.

2) Divide the following number 20 with 5.

Solution

The division is 20/5=4.

These are the notes of the basic math.
