8
Objectives Grade A Rearrange formulae where the variable appears twice

9
What is: If a=3 b=2 c=-1 a + b + c ab 2a + 3b – 4c When two letters are beside each other it means they multiply each other When a number and a letter are beside each other it means they multiply each other

10
What is: If a=3 b=2 c=-1 3 + 2 + -1 = 3 x 2 = 2 x 3 + 3 x 2 – 4 x -1 = Add a negative number

11
Negative Numbers -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 Adding a positive number Subtracting a negative number Adding a negative number Subtracting a positive number

12
What is: If a=3 b=2 c=-1 3 + 2 + -1 = 3 x 2 = 2 x 3 + 3 x 2 – 4 x -1 = B O D M A S 4 6 16 Add a negative number Negative times a negative

13
Substitute A=-7, D=30 to work out what the value of C

16
Create an equation to work out the value of x

17
How many x’s ?3x How many degrees are their around a point? 360

18
Create an equation to work out the value of x 3x + 60 = 360 Now solve 3x = 300 - 60 ÷ 3 x = 100

19
P=3q + 5 Make q the subject Just like solving equations we do the same to both sides Just like solving equations we do the same to both sides

20
P=3q + 5 Make q the subject P = 3q + 5 -5 P - 5 = 3q ÷ 3

21
Rearranging formulae when expression includes brackets – make x the subject ÷ a + b

22
Make c the subject - 32 x 5 ÷ 9

23
Pythagoras Theorem a 2 + b 2 = c 2

24
Make a the subject - b 2

25
Pythagoras Theorem a 2 + b 2 = c 2 Make b the subject - a 2

26
Pythagoras Theorem a 2 + b 2 = c 2 Make c the subject

27
Pendulum swing Activity – substitute g stands for gravity and in GCSE maths we round gravity to 10 m/sec/sec

28
Pendulum swing Activity – substitute g stands for gravity and in GCSE maths we round gravity to 10 m/sec/sec

29
Pendulum swing Activity – substitute l is the length of the pendulum. Lets call it 40m T is the time it takes in seconds to make one swing

30
Pendulum swing Activity – substitute

31
Pendulum swing make l, the length, the subject How long should it take for one swing of the pendulum? Then we need to make l the subject as we know T

32
Pendulum swing make l, the length, the subject 2 π is a number Π is a number a little over 3, it is not a variable Divide by 2 π Square

33
Divide by 2 π Square Times by g

34
Variable appears in more than one place
