INTEGERS, POWERS AND ROOTS
A CUBE NUMBER is the result we get when multiplying a number by itself three times
Eg. 4 'cubed' = 4 x 4 x 4 = 64 Finding the CUBE ROOT of a number is the inverse operation of cubing that number Eg. 2 x 2 x 2 = 8 --> 3√8 = 2 A DENOMINATOR is the value on the bottom of a fraction The FACTORS of a number are all of the numbers that will divide into that number exactly Eg. Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 The HIGHEST COMMON FACTOR (HCF) is the highest number that can be divided exactly into each of two or more numbers Eg. The HCF of 24 and 56 is 8 An INTEGER is a positive or negative whole number The LOWEST COMMON MULTIPLE (LCM) is the lowest value that is a multiple of two or more given quantities Eg. The LCM of 24 and 56 is 168 |
A MULTIPLE of a number is found by multiplying that number by 1, 2, 3, 4, ...
Eg. Multiples of 3 are 3, 6, 9, 12, 15, ... A NUMERATOR is the value on the top of a fraction PRIME FACTOR DECOMPOSITION of a number means writing it as a product of prime factors Eg. The Prime Factor Decomposition of 180 = 2 x 2 x 3 x 3 x 5 A PRIME NUMBER has exactly two factors, itself and 1 Eg. The first 10 Prime Numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 A SQUARE NUMBER is the result we get when we multiply a number by itself Eg. 3 'squared' = 3 x 3 = 9 Finding the SQUARE ROOT of a number is the inverse operation of squaring that number Eg. 5 x 5 = 25 --> √25 = 5 |
SEQUENCES
FINITE sequences have a limited number of terms\
An INFINITE sequence has an unlimited number of terms and continues forever A NUMBER SEQUENCE is a set of numbers in a given order which follow a pattern |
To find the value of a particular term in a sequence dependant on its position in the sequence, we use a POSITION-TO-TERM rule (Also known as an nth term)
Each value in a number sequence is called a TERM |
