Rules of inequalities

Rule 1 :the same amount on each side of inequality is still the same and true

Rule2:if you subtract the same amount from each inequality the answer is still the same snd true

Rule3:if we multiply both sides of an inequality by a positive number,the inequality does not change

Rule 4:if we multiply both sides of an inequality by n negative number the inequality sign must be reversed

Average

You need to add the numbers and devide the total amount by the number of items

Commutative,Associative and Distributive laws

Distributive law:when we multiply a number by the sum of two numbers,it is the same as multiplying first and adding the two products.

Example:2x(3+4)=2x3+2x4

Associative law:when we add and multiply three numbers,it does not matter which 2 we add or multiply.

Example:(2+1)+3=2+(1+3)

Commutative law:when you add and multiply two numbers.

Example:6+2=2+6

Types of numbers

Square roots

The square root is the oppsite of the square and is the number which when mulitiplied by itself gives the final figure

Example:square root of 4=2

Numbers that are squared

The squared of a number is the multiplied by itself and is represented by the symbol^2 written the number as in 4^2

Example:x^2=x^2 or 4^2=16

Odd numbers

Odd numbers are numbers that are not even

Examples:1,3,5,7,9...

Even numbers

Even numbers are multiplies by 2.All even numbers can therefore be divided by 2 to give a whole answer

Examples:2,4,6,8,10...

Prime numbers

A prime number can only be divided by 1 and itself to give a whole number answer

Example:1,2,3,5,7...

Intergers

The consist of all whole numbers, their negattive as well as zero

Example:-6,-5,-4,-3,-2,-1,0,1,2,3,5

Whole numbers

Numbers that we use to count are whole numbers

Example:1,2,3,4....

Number line

Subtopic

Example:-3-3=0(means you have to move from -3 three places to the right hand sight

The numbers on the right hand sight is positive numbers and the numbers on the left hand sight is negative

The basics operations of numbers

Dividing

Example:-20/5=-4

Dividing is when you divide two or more numbers with each other.

Multiplying

Multiplying is the same as adding.Instead of adding 3 groups of 4 you can multiply 3 by 4 to get the same answer.

Example:5x3=15

3of4=12

(-+-=+) Example:-3x-4=12

-x+=-(Example:-3x4=-12

The text outlines various mathematical concepts and operations, starting with the process of finding the average by adding numbers and dividing by the count of items. It explains the number line, distinguishing between positive numbers on the right and negative numbers on the left.
