- copy all data from the sheet above

- paste in a new spreadsheet

- plot 5 single bar graphs (fav colour, fav food, fav sports, fav holiday, fav teacher)

- put a title and label both the horizontal and vertical axis

 

A = 1, B = 3, C = 5, D = 7, E = 9

 

DE – AB

 

DE = D x E = 7 x 9 = 63

 

AB = A x B = 1 x 3 = 3

 

63 – 3 = 60

 

-       Do the exponent first

 

7B^2                                                    common mistake (wrong)

= 7 x B^2                                             7B^2                                        

= 7 x 9                                                 = (7 x 3)^2

= 63                                                     = 21^2 x

 

 

2C^3 – 2A^1

= 2 x C^3  – 2 x A^1

= 2 x 5^3 – 2 x 1^1=

= 2 x 125 – 2 x 1

= 250 – 2

= 248

 

 

A^0 + B^0 + C^0 + D^0 + E^0

 

Anything to the power of zero = 1; Kwok^0 = 1

 

A^0 + B^0 + C^0 + D^0 + E^0

1 + 1 + 1 + 1 + 1

= 5
