The number +, - , * ,/ with zero.

            The Number  +,  - , * , / with Zero.    
This is basic maths for kids. this is basic for beginners level students. It is a basic maths question for exams point of view.
1)Any number adding with zero: is the number itself.

 E.g:
         a) 3 + 0 = 3
         b) 0 + 3 = 3
       
2)Any number subtracting with zero: is the number itself.

 E.g:
          a)3 - 0 = 3
          b)0 - 3 = -3

3)Any number multiplied with zero: is zero.

 E.g:
         a) 3 * 0 = 0
         b)0 * 3 = 0

3)Any number divided with zero: is zero.

 E.g:
            a) 3 / 0 = 0
           
          note: BY HEART THIS SENTENCE.U WILL NEVER WRONG.AT LEAST IN SILLY MISTAKES.  it is called as a basic maths for competitive exams.

How many types of numbers have?

                                                                 Numbers 
basic maths:
This is a generally asked in basic maths for competitive exams.it is also used for basic maths for beginners for students in each respective class level.
                                               
              There are different types of numbers. They are:

              1) Natural number.  e.g ( 1,2,3,4,5,6,7,8,9,10....)

              2) whole number. e.g ( 0,1,2,3,4,5,6,7,8,9,10....)

              3) Integers. e.g ( 0,+1,-1,+2,-2.....).

             4)Real numbers(decimal number): These numbers are also called as imaginary numbers.
                                   
                     They are again divided into two: They are Rational and Irrational numbers.


Rational numbers: the e.g root of positive numbers.

Irrational numbers: the e.g root of negative numbers.


                  5) Prime numbers:  The number comes in its tables. e.g ( 1,2,3,5,7,....)

                  6)Even numbers: The easiest way to remember is 2 table.
                                                e.g ( 2,4,6,8,10,12,14,16,18,20....)
                           
                  7)Odd numbers: The easiest way to remember is other than the 2 tables.
                                                e.g ( 1,3,5,7,9,11,13,15,17,19,21....)  

Basics in fractions.

Basic mathematics.these are a basic maths question.it is also used in basic maths for competitive exams. These basic maths formulas are compulsory applicable in solving Algebra problems.


Addition and subtraction of two fractions:

1) 2/3 + 4/5  =2*5 + 4*3 / 3*5
                     =10/15+ 12/15
                     =10 + 12/15
                     =24/15( divisible by 3 table )
                     =8/5
     
      In the above example first, we should make the denominators with the same number.
So that cross multiple the numbers.

2) 2/3 - 4/5  =2*5 - 4*3 / 3*5
                     =10/15 - 12/15
                     =10 - 12/15
                     = - 24/15( divisible by 3 table ) n                                       get bigger number sign.
                     = - 8/5

Multiplication and Division of two numbers:

 1) 2/3 * 4/5  =2 * 4 / 3 * 5
                     = 8 / 15
                   
         In the above example, numerator numbers will multiply and denominator number will multiply.
         
  2)   2/3   /   4/5  =2/3   /  4/5
                             =2/3 *  5/4(in this step by multiply sign will come and get the reciprocal number of 4/5.

                             =2 * 10/ 3 * 4 ( in this same as multiply)
                             =20/12

                             =10/6 ( divisible by 2 tables in one time.)
                             =5/3 ( divisible by again 2 tables).


       So, students don't make silly mistakes.

      

Examples:

Basic maths 

These basic maths for beginners.

1) + 5 - 3= 2

The number will get minus n get the bigger number sign.
    the i.e plus sign means if u put + sign to the number (+2) then also do or else u will only write 2 it will also do.

      Which is easy and many students do correct answer of this sign convention.

In the above sum, dull students do see the middle sign i.e +, they do 5-3 =2  and forget to give a sign . Even though they will right.
These are basic maths skill and also a basic maths test.  

2) - 5 + 3 = - 2

The number will get minus n get the bigger number sign. here, the sign will be minus.
       
      Many students do the correct answer to this sign convention.
     Students do the number minus and forget to give minus sign to that number.

In the above sum, dull students do see the middle sign i.e-, they do 5+3 =8 and forget to give a sign.

Here they will be wrong.
So, please follow this basic clearly which easy but should not avoid for higher studies without knowing basics.this is used in basic competitive exams test.


Note:  + -=  -
           - + = -
These basic maths formulas are important while solving a problem.

Sign for Addition and subtraction:

  These are the simple Basic maths formulas. It is also Basics for beginners.   

3)  + 1st number - 2nd number=operation(do) is minus and get the bigger number sign.

4) -1st number + 2nd number=operation(do) is minus and get the bigger number sign  .

Examples:

Basic mathematics uses these formulas in every addition and summation.it is compulsory for basic maths for beginners.


1) +5 + 3 = + 8



The number will get plus n get the bigger number sign.
    
      Which is easy many students do correct answer of this sign convention? Almost everyone.

2) -5 - 3 = - 8

The number will get plus n get the bigger number sign.
    
      Which is the typical one?
      Many students do the wrong answer to this sign convention.
     Students do the number minus and give minus sign to that number.

- - = -
The above one is used in basic skill test exams.it is a basic maths test questions too. 

i.e 5-3=2 and the sign gives minus.

Answer = -2

Note:  - -   =  -
           + + = +
