### Indices Basics

Indices rules: 1) 1 to the power of anything is 1. 2) Anything to the power of 1 is itself. 3) Anything to the power of 0 is 1. 4) When you divide powers, you subtarct them. 5) When you multiply the powers, you add them. 6) Anything to the power of a half is its square root. 7) Anything to the power of a third is its cube root.

### Algebra Basics

I know you all hate algebra, but once you've got these rules under your belt its easy. Seriously. 1) You can only put the same letters together. Like how it wouldnt make sense to put a Bob Marley record in a Led Zeppelin record sleeve, two different letters don't mix. 2) A letter and a number together means multiply. Example: 2x. 3) The Golden Rule: You must do to one side, what you do to the other. For example, if you are buying a birthday present for your two siblings, you must treat them the same to be in balance. You wouldn't spend £13 on one and £14.89 on the other. In a similar manner, you would keep both sides of an equation equal.

### Example Questions

1) 17 to the power of 0 2) 23 to the power of 1 3) 0 to the power of 1 4) 1 to the power of 0 5) The square root of 15 to the power of the cube root of 9

### Formula for Linear Graphs

y=mx+c! This should be engraved in your brain! It is the general equation for a straight line, and remembering it will make your life so much easier. Honestly. Remember: m=gradient, y=y-intercept (where the line crosses).
