We can work the remainder by using division, and one of the most common methods to use is long division. (Here I would present the method on a whiteboard)

As we can see, the closest multiple of 8 t...

It is crucial to know that three thirds make up 1.

If there are 9 lots of 1, then we would need 9 times the amount of thirds that make up 1.

Therefore, there are (9 x 3) thirds in 9, which e...

We must identify the like terms and combine them:

4x + 5y + 6x - 7y

4x + 6x = 10x

5y - 7y = -2y

Therefore, the simplified ex...

When it comes to equations that have more than one symbol, you must always follow BODMAS: Brackets, Order, Division, Multiplication, Addition, Subtraction.

The equation we have is 2 + 8 x 3, using ...

Before we begin to approach this question, we first write down all the relevant formulae for this trigonometry question. We can see that we will need the double angle formulae (on account of the presence ...
