Quick Reference

• Removing brackets 1
  In order to simplify mathematical expressions, it is frequently necessary to 'remove brackets'. This leaflet explains the rules for replacing bracketed terms, with non-bracketed equivalents.
• Removing brackets 2
  In this leaflet, we show you the correct procedure for writing expressions of the form (a+b)(c+d) in an alternative form, without brackets.

Video

A transcript of each video should be available in the Teach Yourself section above.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.

• Expanding & Removing Brackets
  In this unit we see how to expand an expression containing brackets. By this we mean to rewrite the expression in an equivalent form without any brackets in. Fluency with this sort of algebraic manipulation is an essential skill which is vital for further study. (Mathtutor Video Tutorial)
