Remember this rhyme..

Hey diddle diddle, the medians the middle

You add and divide for the mean

The modes the one you see the most

& the range is the difference between

## Simplifying

Simplify 3(2a + 3b) + 4(2a + 4b)

Simplify 5(3a +2b) - 2(2a + 3b)

b x b x b =

p x q x r =

2a x 3b =

2p x 2q x 2r =

## Simplifying

1) 6a + 9b + 8a + 16b

14a + 25b

2) 15a + 10b - 4a - 6b

## Factorising

1) 2(3a + 4b + 2c)

2) x2(x2 + x + 1)

3) 2y( y2 + 4y + 5)

4) a(b + c + d)

5) 3(x + 4)

## Algebra

Solve 2y - 4 = 9

Solve 4( 2x -3) = 5x + 7

6 of 8

2y - 4 = 9

2y = 13

y = 6.5

8x - 12 = 5x + 7
