They are numbers that are formed by linear combinations of square roots, cube roots (and other higher roots) of numbers which cannot be simplified into ratios of integers (ie rational numbers). The linear combinations may also contain integers.
A linear combination is simply a way of saying so many sqrt(2)s plus that many cuberoot(7)s etc.

What is surds in algebra?
Irrational numbers
Why are surds useful in math?
They define irrational numbers
Are surd's rational?
No because surds are irrational numbers
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.
How do you work out surds?
Surds are normally irrational numbers but they can be simplified for instance the square root of 12 can be expressed as 2 times the square root of 3
How do you find surds?
Surds are normally irrational numbers.
What is surds in algebra?
Irrational numbers
What is the difference between surds and irrationals?
Roots that are irrational are called surds. There are irrational numbers that are not surds since they are not roots of any equation. For example, Pi. Rational roots, such as square root of 4, are not surds.
Why are irrational numbers called surds?
Irrational number are NOT called surds. For example, pi is irrational but it is not a surd.Surds are a very small subset of irrational numbers.

Are surds plant roots?
No. Surds are a part of maths, and are the opposite of powers.
What is the difference between surds and irrational numbers?
A surd is a number expressed as a square root (or some other root). Such roots are usually irrational; but irrational numbers also include other numbers, which CAN'T be expressed as the root of a rational number. For example, pi and e.
