Like Terms

Today for Maths we have been doing algebra and learning how to add and subtract algebraic equations. Today we did like terms, They are terms that contain the same variables such as N or X.

I learnt that if you add them together and multiply them together it will have a different outcome such as:

n+n+n = 3n

And

n x n x n = n3

We learnt how to work out some equations like this

3n+7 – 9n  =___

3n+ -9n = -6w

Answer: 3n+7 – 9n = 6w + 7
