Inequalities
Inequalities are a really common 'cross-over' topic and it's important to know how to write and represent them. Watch this short clip for an overview on writing and representing inequalities.
Error Intervals
Another common 'cross-over' topic is error intervals. The main thing here is to take notice of the degree of accuracy the number has been rounded to. We half this to find the upper and lower bounds and our inequality signs always point down to show less than the upper bound but greater than or equal to the lower bound.
