Providing the radical has then just add/subtract.
e.g.
4sqrt(3) + (/-)7sqrt(3) .
The radical has tha same coefficient of 'sqrt(3)'
Hence it becomes 11sqrt(3) ( or - 3sqrt(3))
However, if the radicals are different then
4sqrt(3) + 7sqrt(2) . cannot be taken any further.

Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..
No. Radical(9) is +3 or -3, both of which are rational.
