<br>
We need to go 6 blocks east and 4 blocks north, in any order.  The number of ways we can do that is the number of ways we can arrange the letters EEEEEENNNN.<br>
By a well-known counting principle, the number of ways we can do that is<br>
{{{C(10,4)=(10!)/((6!)(4!)) = (10*9*8*7)/(4*3*2*1) = 210}}}<br>
