GCSE Maths Formula Sheet
Rules of Indices
Rule 1: When you multiply indices of the same number you add the powers.
For example: 54x 53= 54+3= 57
Rule 2: When you divide indices of the same number you subtract the powers.
For example:
Rule 3: Indices outside a bracket multiply.
For example: (32)4 = 32 x 4 = 38
Rule 4: Negative indices mean reciprocal, i.e. 'one over....' or 'put on the
bottom of a fraction'.
For example:
Rule 5: When the power is a fraction the top of the fraction (numerator) is a
power and the bottom of the fraction is a root.
For example:
Rule 6: Anything to a power of 1 is just itself and we normally don't bother
putting the 1 there.
For example: 51 is just 5.
Anything to a power of 0 is equal to 1, it doesn't matter what number it is!
For example: 100 = 1, 20 = 1, x0 = 1, etc.

The equation of a straight line is y = mx + c
The gradient, m:
Quadratic functions are written in the form y = ax2 + bx + c
Cubics are in the form y = ax3 + bx2 + cx + d
