Re: translate math words into

I am not surprised you find this confusing.  This looks like a very old book and the English is ancient too.  There are more modern ways for learning about this.  I'll have a go at 'translating' it into math.

If S is a square number then R = root =    √ S [ I'm using => as the symbol for  'this means that' or 'implies' or 'therefore' ]

This idea is used again and again in these 5 examples.

eg.1  √ S = 5   => S = 25

eg.2  S/3 = 4R  => S = 12R  But S = RxR (R times R) so R = 12 and S = 144

eg.3  5xS = 10 x R  divide both by 5 => S = 2R  => R = 2 and S = 4

eg.4  5S = 80   => S = 80/5 = 16  => R = 4

eg.5  S/2 = 18   => S = 36   => R = 6

Hope that helps,

Bob
