makes my brains all mushy. This pattern writing thing? Not so much fun. Well worth it, but not so much fun.
I like to write out my math, then check with calculator. That way, if I wonder about my logic later on, it's all right there. Sort of.

Rehearsal & Performance for the Ann Arbor Dance Classics' Anniversary Cruise aboard the Carnival Sensation on the last day at sea, Friday August 19, 2016. The crew used fancy lighting - which made for a great performance - but hard to photograph! These 673 pictures are about 22% of all the pictures I took - I will let you do the math. The dancers performed on the ship's Fantasia Lounge, the largest stage on the cruise ship. The cruise celebrated the studio's 20th Anniversary and visited the Western Caribbean from August 15 - 20, 2016.

Miles (6), who is homeschooled, finished his 1st Grade math curriculum today. He was very proud of himself.
See collaboration in action!

At Casey Elementary School on Camp Casey Jan. 14, students and parents take part in the school's second annual Math Madness workshop, which aimed to build math proficiency by using games and other activities to make the subject enjoyable for youngsters. In one of those activities, for example, competing groups had to use 20 strands of uncooked spaghetti and about a yard of masking tape to create the tallest possible structure that would support a marshmallow for at least 30 seconds without collapsing. - U.S. Army photo by Pfc.

Prepare to be educated!
1) The above is called Pascal's triangle
2) The number of rows is infinite (although you'll get tired of calculating rows).
3) To make a new row, add two consecutive numbers in a row and put the sum between the numbers, on a new row below. Eg. 5+10 is 15.
4) The top number is 1 (not shown) and is in row 0.
5) If you ever care to expand (x+y)^n (n is an integer), the coefficient of the terms in this expansion can be found in row n. Eg. (x+y)^3 = x^3 + 3(x^2)y + 3xy^2 + y^3 see? 1,3,3,1, which is row 3. This is also called the binomial expansion (bi since there are two terms, x and y)
6) Suppose you need to know how many different groups of 2 people can be made using 4 people. We can see that the groups would be persons: 1&2, 1&3, 1&4, 2&3, 2&4, 3&4, so 6 groups. Now that was easy with only 4 people, but suppose you had 20 people and needed to figure out how many groups of 5 could be created. You don't want to do this by hand! The mathematical term for what we want is called a combination: the number of groups of size r that can be formed using n objects, or nCr. Going back to the original example, look in the 4th row (n = 4) and in the 2nd diagonal (r = 2, where diagonal r=0 is the diagonal of 1s). We find 6!
7) Since nCr = nC(n-r), the triangle is symmetric. Eg. Using 3 people, there are 3 groups of size 1 (r=1)and 3 groups of size 2 (r=2), so 3C1 = 3C(3-2) = 3C1. The actual definition of a combination is nCr =n!/(r!*(n-r)!), where n! = n*(n-1)*(n-2)*...*2*1. The "!" is called "factorial". Eg. 5! = 5*4*3*2*1 = 120. You can do this computation on a calculator, so you don't need the whole triangle to calculate 20C5.
8) The sum of the numbers in a row is a power of 2. Eg 1+5+10+10+5+1 = 32 = 2^5, which were the digits of row 5 in the table.
9) Pascal's triangle is really easy for high-schoolers to learn, and thus they can expand (x+y)^n easier than normal.
Isn't math great?
