# Algebra for Kids

*(scroll this section to read all)*

Knowing how to work with algebraic equations and algebra in general is extremely useful in day to day life as well as a real necessity when it comes to working well , especially in higher level occupations. It also helps to develop critical thinking ability too.

Working with spreadsheets (like Microsoft Excel which is the de-facto standard) often involves algebra and spreadsheet s are used extensively in all manner of business situations (e.g. market research, accountancy, banking, economics and, indeed, any business management position) . Science, of course, requires an excellent understanding of algebra, so jobs such as chemical, mechanical, civil or electrical engineers, astronomers, chemists, biologists, physicists and even computer scientists will use it all the time. It goes without saying that mathematicians and statisticians will heavily utilise their algebra skills.

After you have a good understanding of Algebra you should be able to:

- work out 'simultaneous equations' of two number sentences with two unknown values
- convert descriptive number problems into algebraic problems
- use correct orders of operations e.g. BIDMAS
- understand arithmetic progressions
- become accustomed to letters or symbol representing an unknown value
- manipulate and simplify algebraic expressions
- work with quadratics
- use graphing to estimate values
- solve linear equations of one variable

Have a look at the links below to see some great schemes and learning videos. In this way you can learn everything you need to know about algebra. You will also be able to have fallen while you're learning.
