Maths - Basic Algebra

This youtube goes through the basic functions of + - x / and the effect that this has on the equation.

Basically you need to isolate the unknown (x) on one side of the equation so that you can find out what its value is.  The theory is that what you do to one side you do to the other.  This also means that if you take a value from one side of the equation to the other it changes from + to - (or visa versa) or it changes from x to / (of visa versa).

Here is a youtube which shows you how to simplify and work with brackets in basic algebra.

Paper folding is good for you and teaches you lots of things

I was quite amazed to read that Paper folding - Origami is very educational i.e. develops lots of skills.

Even though you don't realise it, you are learning as you are doing a fun thing. Things that one develops, when you are doing Origami:

• Eye hand co-ordination
• Creativity
• Following directions i.e. Read vs. understand skills
• Attention
• Manual dexterity
• Patience
• Temporal spatial skills
• Reasoning
• Visual motor skills
• Processing Skills
• Maths concepts (Geometry, proportion, measurement, symmetry, fractions)
• Cultural studies (Oriental)

Paper folding is also good for adults as its relaxing. It also helps people recovering from hand injuries regain their control over their hand movements and helps build muscles.
