How To Create Algebra From Words
|Education : Maths|
Often when you are asked to solve a question you will need to write it in mathematical form.
Let's say you are told Fred has ?30 and needs ?65 to buy a Playstation. How much money does he need to buy it?
Well, you could write it like this:
30 + x = 65, with 'x' being the unknown
Now we re-arrange to get:
x = 65 - 30 = 35
So he needs ?35. Whilst this might be immediately obvious with this simple question, with harder ones it can make them much easier to solve.
