About this lesson
This is the next video in the General Maths series. Looking at Directed Numbers I spend some time explaining what directed numbers are and how we can use number lines to express them. I then look at how we can add, subtract, multiply and divide the directed numbers and the rules we need to apply when doing so. There are lots of worked examples all backed by easy to understand and clear theory.
