... Surds are numbers left in 'square root form' (or 'cube root form' etc). They are therefore irrational numbers. The reason we leave them as surds is because in decimal form they would go on forever and so this is a very awkward way of writing them. Addition and Subtraction of Surds When adding and su ...

... The numerical value of any measurement will always contain some uncertainty. Suppose, for example, that you are measuring one side of a square piece of paper as shown above. You could say that the paper is about 2.5 cm wide and you would be correct. This measurement, however, would be unsatisfactory ...
