Solving inequalities seems to be a favourite maths GCSE question …
although it’s fairly useless in real life. Even though we do tend to think in inequalities (see top tips) …. I haven’t really come across a great application. It’s good practice for linear equation solving – and can look interesting on a whiteboard – but that’s about it. Sorry. Unless you know any different? Please post a comment below!
● Inequalities can be treated in the same way as linear equations
● You’re really just mathematically showing everyday speech phrases like “at least” or “at most” or “no more than” or “no less than” can all be shown as an inequality
● It’s pretty unlikely that you’ll write inequalities in real life … but you’ll certainly use them all the time!
● The most common use is making sure you’ve got enough money. All your payments must be less than or equal to your income.
