A PATTERN MULTIPLES OF 5 IF YOU MULTIPLY EACH MEMBER OF THE SET OF WHOLE NUMBER BY 5, YOU FORM THE SET LIST BELOW: (0,5,10,15,20,25,30,35,40,45…..) A NAME FOR THIS SET IS THE SET OF MULTIPLES OF 5.

EVEN NUMBERS  IF

YOU MULTIPLY EACH MEMBER OF THE SET OF WHOLE NUMBER BY 2, FORM THE SET LIST BELOW . (0,2,4,6,8,10,12,14,16,18,20…..) THIS SET IS CALLED THE SET OF MULTIPLES OF 2 OR THE SET OF EVEN NUMBERS. IF n STAND FOR ANY WHOLE NUMBER, THEN 2 ×n STAND FOR AN EVEN NUMBER. YOU CAN ABBREAVIATE 2 ×n AS 2n, WHICH IS READ two n.

MULTIPLES 3 AND OF 9  {3,6,9,12,15,18,21,24,27,30,33,36,39,……….} 1+2 1+5 1+8 2+1 2+4 2+7 3+0 3+3 3+6 3+9

3 6 9 3 6 9 3

6 9 3 6 9

 EACH

NUMBER REPRESENTED THE TOP ROW CAN BE DEVIDED BY3AND THE REMAINDER WILL BE 0.WE SAY THAT EACH OF THESE NUMBERS IS DIVISIBLE BY 3.

 WHAT

NUMERAL SHOULD REPLACE IN THE LAST ROWIF THE PATTERNISTO CONTINUE ? TO OBTAIN 3 FROM THE DIGITS OF 12 TO OBTAIN 3.

PRIME NUMBER 2=1 X 2 =2 X 1 

6=1X6=3X2 =6X1=2X3

DOES 2 HAVE ANY WHOLE NUMBER FACTOR BESIDE 1 AND THE NUMBER 2 ITSELF? EVERYWHOLE NUMBER HAS ITSELF AND 1 AS FACTORS, BUT SOME HAVE OTHER WHOLE NUMBER FACTORS. FOR EXAMPLE, 6 HAS THE FACTORS 1,2,3 AND 6

IF A WHOLE NUMBER IS GREATER THAN 1 AND HAS ONLY ITSELF AND 1 AS WHOLE NUMBER FACTORS, IT IS CALLED A PRIME NUMBER ORA PRIME



THEY ARE:

2,3,5,7,11,13,17,19,23,29,31,37,41,43,47, 53,59,61,67,71,73,79,83,89,97  Is

2 a prime number ? Why ? Since other multiples of 2 cannot be primes,theyare marked .

 Is

3 a prime ?why ?since other multiples of 3 cannot be primes, those not ready marked are marked .

 The

next prime after 7 is 11 . Name the multiples of 11 less than 100. since all of them have been marked, we can stop the numeral remaining unmarked name prime numbers.

SECOND POWER OF WHOLE NUMBER

36

4x 4 , 42 all name the same number . You may call 4 four squared or the square of 4. can you think of a reason why ? Which square above would you associate with 1 ? With 2 ? With 3 ? With 5? With 6?
