No prior knowledge needed and emphasis is on fun.

We’re a small friendly group.

All materials provided .Just bring pen and paper.

There is no pressure as you work at your own pace. 

We cover whatever group suggests. Failing that I will always come up with something.

In past have covered topics like use of scientific calculator, different methods of long multiplication (see exercise on Russian multiplication)percentages and even algebra which pleasantly surprised many in group.

Contact me and do come along and try us out.

Maths puzzle

Russian multiplication

Example 

 26 x 32

Method

Represent numbers as 2 columns 

Halve first column ignoring any remainders and double second column 

Keep doing this until number in first column is 1

             26.            32. X

              13.             64

               6.              128. x

               3.               256

               1.                512

Then cross out any lines where number in left column is even (marked by X  above)

Finally add remaining numbers in right hand column (ie 64 + 256 + 512)

This gives you correct answer of 832  Believe it or not !!
