... Consider the first step. It moves to either (1,0) or (1,1). It cannot go down to (1,-1) because it is required that the path never goes below the x-axis. Case 1: the first step moves to (1,0). According to our definition of Mn , we know that the number of ways to move from (0,0) to (1,0) is M2 . Nex ...

Rational Numbers (Decimals)
... A decimal representation that has a string of digits (other than zero) that repeats. (The first string of repeating digits is called the repetend). For example, 0.1234545 . . . = 0.12345 has the repetend 45. The convention is to write a bar over the repetend instead of writing ellipses. 2. Repeating ...

... He wrote several mathematical texts that, among other things, introduced Europe to the Hindu-Arabic notation for numbers. Even though his books had to be transcribed by hand, they were widely circulated. In his best known book, Liber Abaci, published in 1202, he posed the following problem: A man pu ...

Pattern 3
... When first encountering the symbol t n , it is natural to think that it means to multiply t by n since we often indicate multiplication by parentheses and writing two terms next to each other. For example, when we see 3 x 5 , we know that this means to distribute the 3 through the parenthes ...
