Inequalities' :
< smaller than
bigger than=>
If there is a line under the symbol its equal
On a number line if the dot is shaded in it may be equal
If hollow it is not equal to
Equation on a line
m=gradient
c=y intercept
y=mx+c
rise divided by run
Rounding to 1 and 2 decimal
If the number is 5 or above it rounds up
2 decimal places you look at the 3rd number after the decimal place
If the last number is 4 or below it rounds fown
Significant number
2nd significant number is the second number
etc
First significant number is the first number
Sequences :
7,12,17,22
Difference of 5
5n+2
Rounding to whole number
Anything bigger than 0.5 goes up
Anything before 0.5 goes down
Estimating calculations
Estimate =not exact but close enough that you can do in head
You can estimate by rounding
Gradient of a line :
If line go down=negative
If line goes up=positive
Gradient
y Divide x
Y2-Y1 divided by x2-x1
Solving equations
Need to simplify so one side is x
