I wish you could replace my math teacher right about now. — jdudeJmusicAforlifeC
I’m available for math tutoring at any level in New York City at a rate of $60 per hour. I have a BS in Math from MIT and an MA in Math Education from NYU, and I’m certified to teach math in grades 5 through 12 in New York City, which I did for a year and a half. That’s not important, though. What really matters is that I’m an excellent teacher. Watch my videos below to see for yourself. If you, your child, or someone you know needs help with math, feel free to contact me using the form at the bottom of this page.
Math: Conditional Probability
That was the first 11 minute video that I actually watched and didn’t just skip through. — Rudra13
I use OJ Simpson, among other things, to explain how the probability of an event can change if the conditions of that event change.
Math: Differential Equations
Sweet man, you made it very understandable, thank you. — cptrecon
I introduce differential equations using classic physics problems such as gravity and driving down the street.
Math: Negative Times Negative Equals Positive
Yay! Now it makes sense. — Secnarf2
We all had it drilled into our heads that a negative number times a negative number equals a positive number, but why is this?
Math: Slope of a Line
I got an A- on my slope math test thanks to you. — jaygonzalez93
The slope of a line measures how steep the line is.
Math: Triangles Sum to 180°
Thanks for your help on my homework. — Dorgoth12
If you take a triangle, cut off the corners, and line them up, they will make a straight line (180°). Here’s why.

SAT Study Guide
I’ve been working on an open source, free, easy to understand SAT study guide for the math section. Ever since I saw the 1000 page, ridiculously complicated, $50 SAT study guide at Barnes & Noble, I knew there must be a better way. You can download the guide along with the source code using the links below. It’s far from finished, but it’s a good start!

Now I have read more, I see you live in New York. Not a surprise.
I also do some tutoring. Maybe you will be interested in this incident: To get the student’s interest, I did the trick where you show the student 7 cards with numbers on them, and she says whether the number she is thinking of is on each of the cards (she is thinking of a number from 1 to 100). Then you can tell her what number she was thinking of. I am sure you will know how this works, if not, I didn’t explain it well enough. This can be very effective.
My goal for the hour was to prove that the sum of the angles of a triangle is 180 degrees.
So (having already established my mind reading ability) I said, draw a triangle, but don’t show it to me — now measure the angles, but don’t tell me what they are — now add them up — concentrate on that nunber — it is 180!
At this point her mother said He’s not reading your mind! He was going to say 180 no matter what triangle you drew!
I thought that was good because it meant that the mother (who also didn’t know the theorem) had got the idea that there was a theorem here. Then that gave me a good lead in to :why is it always 180?
Here is a terrific math “trick” that always blows people away until they figure it out:

For me, the most effective way of demonstrating that the angles of a triangle add up to 180° is to have kids draw a triangle and actually cut it out. Then they rip the corners off and line them up and behold it forms a straight line! I usually do this AFTER the proof, because they never believe the proof. I say, “do you want to bet?” and they fall out of their chair when they actually do it physically with a triangle they themselves made.
your are good
Hi Philip
I like your videos and came here from the Mony Hall video.
I made some slides that teach children age 7 why a negative times a negative is a positive. I don’t think my cartoon approach with children has been done before.
The interesting bit explaining -ve Xs -ve can be found from slide 3 here

Thanks, Jonathan. Educators are always welcome here
Hi Philip,
I’m a math teacher from Croatia. I love your videos, especially the visual style of the presentations. Would you mind divulging which software you used to make them?
Thanks in advanced,

Hi Philip,
I need a little help solving a math problem, and having seen a few of your videos in the past i noticed you do a little math tutoring too!
I wondered if you had an email address i could contact you at?
cheers
