Four Operations
These are the some of the fundamentals in maths. We will learn how to add, subtract, multiply and divide. We use all four in lots of different questions in everything we do..

Try MemberstackWorking with negatives
Negatives can be one of the biggest reasons why students lose marks in their exams. Pay close attention to the signs, and think about it in terms of temperature or money.
Rounding
Rounding is used to make numbers more simple. Always look to the right of the number you're rounding to, and remember that anything 5 or above rounds up.
Estimations
Estimating is similar to rounding as we make the numbers more simple, but we then use them to calculate something instead.
Subsitution
We can substitute numbers into equations with letters in order to find the answer to a problem. These are useful when we have to work something out more than once and the variable needs to change.
BIDMAS
You need to follow the order of operations BIDMAS, otherwise the answer can be completely wrong. Pay close attention when there is more than one sign or operation.
Averages and Range
Averages are used to give an overview about a large set of data. The mean, median, mode and range are all types of averages that we can find.
Product of Prime Factors
To find the product of prime factors, you need to divide a number using a factor tree to establish the prime factors, then use indice notation to display this. These are useful for HCF and LCM.
Highest Common Factor and Lowest Common Multiple
We are looking for the highest number that can be divided into two numbers, and the lowest number they can both go into. Use a factor tree to find the product of prime factors or then a venn diagram.
Standard Form
Standard form is used to present numbers using powers of 10. The number must be between 1 and 10.
