1. Simplify the following expressions
A - a + a + a + a + a = 5a
B - a + a + b + b = 2a + 2b
C - b x b + a = b^2 + a
D - a x a x a = a^3
2. Expand 2(3a + 6)
6a + 12
3. Solve the following equations
A - x = 5
B - x = 3
C - x = 33
D - x = 2
4. Make u the subject in the formula p = 4n + 2u
u = (p-2n)/2
5. Make b the subject of the formula p = 2a + 2b
b = 1/2p - a
