KS3 Mathematics Algebra quiz

15 Questions

Quiz Description

In this quiz, we will be looking into algebra which is the study of mathematical symbols and the rules for manipulating these symbols, it is the unifying thread of almost all of mathematics. Before the end of this quiz, you will see that algebra is not just important in class, but in real life, we apply algebra without even noticing. For example, algebra is useful around the house and in analyzing information in the news.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols, there are many operators to which numbers are manipulated. These manipulations are usually done by the order of BODMAS where;

B= Brackets
O=Order
D=Division
M=Multiplication
A=Addition
S=Subtraction

These basic Math operators are used throughout algebra, and arithmetical problems involving all those operations are solved with consideration of the order BODMAS.
Our quizzes are not only on maths, but there are also several quizzes on other science subjects.
By taking the quiz, you will find out how well you are familiar with this topic in Mathematics.
Enjoy!!
