We have below bronze, silver and gold tutorials for Changing the Subject in the Relationships unit of National 5 Mathematics. Bronze tutorials are typically unit assessment standard with the silver tutorials providing typical "exam type" questions as examples. If you can manage these you should try our more advanced gold tutorials containing the more unpleasant "exam type" questions. Typically as you work through the modules, the difficulty of the skills increase by one step ensuring smooth progression. Simply click on the video to play it and pause it at the relevant points for you to attempt the questions. Each tutorial has a corresponding worksheet for you to download if additional practice is required. Make sure you have a pen and paper handy! Once you've mastered the skills, why not try the Pastpaper questions at the bottom of the page?

These are the skills that you should already have mastered with BEFORE you begin studying this National 5 module. If you are unsure, watch the videos and try some questions.

• Solving multi-step equations (MTH 315a)       Bronze       Silver       Gold

Changing the subject of the formula is formally introduced in National 4 Maths and our bronze module recaps some of the more basic "1 step" and "2 step" questions that you should already be familiar with.

VIDEO 94: Outcome 1 - Changing the subject of the formula; one step questions. Grab a pen and your Rigour jotter. Make sure you try all the questions! 

Our silver module builds on "2 step" questions by throwing a few additional operations into the mix and extends further by looking at "3 step" questions.

VIDEO 96: Outcome 1 - Changing the subject of the formula; two step questions. Grab a pen and your Rigour jotter. Make sure you try all the questions! 

If you feel you have mastered these skills why not try this short quiz under exam conditions? You will be provided with instant feedback so be sure to view it. Remember to re-do any video lessons (or use the worksheet) for any questions you answered incorrectly. Once you have completed the quiz, record the score in your profile, go for gold and/or try the past paper questions!

In gold, we explain how to change the subject when the variable you are trying to solve for is the denominator.

Video 98: Outcome 1 - Solving for the denominator. Take notes and attempt all questions. After this, remember to think about your next steps!

Once you have mastered the skills, why not try the pastpaper questions? Click on each question to play the video. Pause it when prompted to do so and have a go yourself first. When you've finished check the solution. You should aim to complete these questions more than once at various stages throughout the year. If you feel that you need more practice at that particular question go to the practice area suggested in the video...good luck!

You have completed this module - well done! Remember to go back and redo any areas of weakness, that's how we improve. If you are happy with all areas, go back to the main menu and pick another topic to practice!
