I figured I'd go ahead and do all the calculations on that page. 
An expanded table with descriptions of what the different numbers mean is on this page.
BIRTHPATH:
The Birthpath Number is arrived at by adding your month, day, and year of birth. The Birthpath Number reveals who you are, what you do best, and whatever natural abilities you have.
Mine is 9...
Talents/Strengths: Inspired, intuitive, creative. Seeks to improve the world.
Areas of Concern: Needs to avoid bad habits, and attend to life's details.
General Leanings: To see the "big picture." To dream the dream.
Practical Expressions: Community leader, organize small business owners.
DAY OF BIRTH:
The Day of Birth Number is a powerful indicator of your point of view and general stance in the world. It is the day of the month on which you were born (apart from the month and year).
Mine is 3...
Talents/Strengths: Outgoing, joy of life, imaginative, enthusiastic.
Areas of Concern: Fears routine. May lack self-discipline, accomplish little.
General Leanings: Energy and ideas in action. Having a good time.
Practical Expressions: Press secretary, party planner, small business promoter.
DESTINY:
It is in this number that the numerical values of your birth name come into play. The Destiny Number is the sum of your first, middle, and last name at birth. Just as the word "Destiny" suggests, this number reveals the purpose, the goal, and direction of your life.
Mine is 8...
Talents/Strengths: Decisive, forceful, good with money. Accomplished.
Areas of Concern: Often lacks feeling for those who stand in the way of goals.
General Leanings: To strive higher, take control, seek power, status.
Practical Expressions: Professional field, or operator of small business franchises.
REALIZATION:
This is the sum total of your Birthpath and your Destiny numbers. The Realization Number shows you what you might accomplish, given your Birthpath and Destiny.
Mine is 8...
(see above for description)
HEART'S DESIRE:
Sometimes we convince ourselves we should or should not do certain things. Yet despite these intellectual considerations, there are certain desires, certain qualities that seem to influence our lives. Will your Heart's Desire (the sum of the vowels in your name) help or hinder you along life's path?
Mine is 7...
Talents/Strengths: A deep thinker, spiritually inclined. Unique, eccentric.
Areas of Concern: Too aloof and fears not living up to high standards. A loner.
General Leanings: To seek answers to life's questions. Observe. Discover.
Practical Expressions: Analytical field. Or self-employment in small business.
PERSONALITY:
Your Heart's Desire (the vowels in your name) examines the inner you (what you most cherish). Your Personality Number is the outer you and is obtained by adding the consonants in your name. Of course, it is always best when the inner and outer parts of you are in harmony.
Mine is 1...
Talents/Strengths: Natural leader, self-sufficient, ambitious.
Areas of Concern: Avoid extremes of bossiness, shyness. Too impulsive.
General Leanings: Standing out from the crowd. Trying new ideas.
Practical Expressions: Political leadership, celebrity, or small business owner.
I noticed that 'small business' comes up in every single number (not just my ones), for 'practical expressions' LOL.
