Using rows to represent mathematical operations and a column for each compound we can draw ourselves a table: Ca W O % 13.9 63.9 22.2 Atomic Mass (Ar) 40 184 16 % / (Ar) 0.348 0.347 1.43 Ratio 1 : 1 : 4 This...

First you need to draw a set of axis and choose a sensible scale, This is detrmined by parts of the equation such as the x and y intercept. Then what we need to do is to make a table of values. We can do X f...

Say we have the brackets (x+1)(x+2) we would expand this by timesing everything in one bracket by everything in the other Demonstrate the claw method in the teaching workplace This gives us x 2 + 2x + 1x +2 ...

The gradient is how much the x value changes when you change the y value by 1. We can find the gradient using 2 coordinates on a line. It is equal to (y1-y2)/(x1-x2) I would do an example on the board

We can see that in any one throw of the die the probablity that the die will land with green side up is 2/6 because it is a fair dice and so has equal chance of landing on any one of the six faces. Since two...
