1. What do =, ,` <, >, ,derepresent?: = equal
`doesn't equal
< smaller than
> larger than
dsmaller or equal to
elarger or equal to
2. Natural number, integer, prime number, square number, fraction, decimal
examples: Natural number: 1, 2, 3, 4, 5
Integer: -3, -2, -1, 0, 1, 2, 3
Prime number: 2, 3, 5, 7, 11
Sqaure number: 1, 4, 9, 16, 25
Fraction: 1/2, 3/8
Decimal: 0.5, 0.003
3. Decimal + and -:
4. Decimal x Decimal:
5. Decimal division:
6. Converting mixed numbers to improper fraction:
7. Adding and subtracting mixed numbers:
,8. Multiplying fractions:
, 9. BIDMAS:
10. Simplifying algebric expressions: For example,
3x + 7x - 5 = 6
10x - 5 = 6
10x = 11
x = 11/10
11. What are Multiples?
Examples?: A multiple of a number is found when you multiply that number by a
positive integer
The first three multiples of 12: 12, 24, 36
12. Lowest common multiple (LCM): OR use list:
24: 24, 48, 72
36: 36, 72
13. Factor example: Factor of 12:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
So 1, 2, 3, 4, 6, 12 are the factors of 12
14. Highest common factor (HCF): OR use list
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Factors of 78: 1, 2, 3, 6, 13, 26, 39, 78
Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The common factors are 1, 2, 3, and 6.
Therefore, the HCF using the listing method is 6
15. What are prime numbers?
What are composite numbers?: They have exactly two factors: 1 and the number
itself
Composite numbers have more than 2 factors
