Study Notes
danielle meredith

Today in Mathematics, we are learning to make study notes.
These can be used to revise information for our tests.


彡 Multiples
Multiples are the result or product of
multiplying a number by another number.

彡 Factors
The numbers that another number can be
divided by.

彡 Prime Number
A prime number is a number that is
greater than one that only has 2 factors
(can only be divided by 1 and itself).

Highest Common Factor (HCF)
The highest common factor is the highest number
that divides exactly into two or more numbers
 
彡 Lowest Common Multiple (LCM)
 The lowest common multiple is the smallest
of the common multiples between two or more
numbers.

ೃ⁀➷ ORDER OF OPERATION: BEDMAS ೃ⁀➷
The order of operations is the order that you solve a mathematical equation. Without B.E.D.M.A.S, equations would be solved incorrectly.

彡 B
B stands for brackets (parentheses)

彡 E
E stands for exponents (the number or letter written
above and to the right of a mathematical expression)

彡 D
D stands for division (splitting a number by another
number)

彡 M
M stands for multiplication (repeated addition
or adding equal groups)
 
彡 A
A stands for addition (adding two numbers together)

彡 S
S stands for subtraction (taking away numbers by other
numbers)

ೃ⁀➷ ROUNDING ೃ⁀➷
Replacing a number with an approximate value that has a shorter, simpler or more explicit representation. Rounding numbers between 1-4 would require rounding down. Rounding numbers between 5-9 would require rounding up.

彡 6.54
Rounding 6.54 to one decimal point would be 6.5 because
it's rounding down the 54 to 50 and removing the unnecessary 0.

彡 7.39
Rounding 7.39 to one decimal point would be 7.4 because
it's rounding up the 39 to 40 and removing the unnecessary 0.

ೃ⁀➷ STANDARD FORM ೃ⁀➷
Standard form is a way of writing down very large or very small numbers easily.

彡 39000
The standard form of 39000 is 39 x 10^4

彡 0.00045
The standard form of 0.00045 is 4.5 x 10^-4
