Simplifying Expressions Simplify the following: a) π₯ + π₯
b) 3π + 4π
c) 2π + 3π + 4π + 6π
d) 9π + 5π‘ β 4π β 7π‘
e) π Γ π Γ π Γ π
f) 5 Γ π Γ π
g) 4π‘ Γ 5π‘
h) π Γ π
i) 6π Γ 5π
Solving Simple Equations Solve:
a) π₯ + 3 = 7
b) π‘ β 2 = 10
c) 15 = π + 10
d) 4π = 40
e) !!= 10
f) π₯! = 100
Expanding brackets Expand: a) 5(π‘ + 2) b) 6(π β 4) c) π(π + 4) d) π(π + π) e) π(π + π β π) f) 5π‘(4π‘ + 3π’) g) (π₯ + 5)(π₯ + 3)

Solving Equations (tougher!) Solve: a) 3π‘ + 4 = 19 b) 5π₯ β 2 = 43 c) 4π β 3 = 2π + 9 d) 7 π + 4 = 42
Sequences
Find the nth term of the following sequences:
a) 8, 11, 14, 17, β¦
b) 4, 9, 14, 24, β¦
c) 7, 14, 21, 28, β¦
d) 100, 90, 80, 70, β¦
Work out the first 4 terms of the sequence:
i) 5n + 2
ii) 7 β 2n
iii) n2 + 3
Substitution
π = 4, π = 10, π = 6 and π = β2
Use the above to work out the following:
i) 4π
ii) 3π + 6
iii) 5π β 8
iv) π! + π
v) !!
vi) ππ + π
vii) !"#!!
