Pretty sure it's against exam rules anyway.

If you get caught you'll be disqualified from all your maths exams. Is like 4-6 marks really worth losing all 300 UMS?

Do this instead:

For example if the question is:
Expand (1+x)^3

We claim the answer is:
1+3x+3x^2+x^3

Check it using a calculator:

We claim (1+x)^3 = 1+3x+3x^2+x^3 holds for any value of x.

Let x=2 for example (you can use any value you like).

LHS: (1+(2))^3=3^3 = 27
RHS: 1+3(2)+3(2)^2+(2)^3 = 1+6+12+8=27

So we can be 99.99% sure our answer is correct.

You didn't say much at all to be honest.

I'm sorry but you need to replace it with a Sinclair C5
