How do you understand Surd's in maths?
How one understands surds depends on the person. If you would
like to know what surds are, or have help understanding surds
A surd is an unresolved radical, meaning that it is a root with
the radical sign still on it. It is easier (and more accurate) to
express it this way than writing it out for many numbers if the
root is irrational. The concept of irrational numbers (which is
what surds are, usually) can be confusing. In short, they are
numbers that are not rational, that is, they cannot be written as a
fraction. When using surds in math, you treat them just as you
would a written out number.
