Path Counting

How to play Path Counting

1. Count shortest paths across a small rectangular grid.
2. Read the prompt carefully and choose an answer, or type into the answer field.
3. After checking, read the explanation. Use “Next round” to continue.
4. Complete ten rounds for a score out of 100. Restart creates a fresh session.

A worked example

How many shortest paths? 3 steps right and 2 steps down, in any order

the answer is 10. Count distinct arrangements of the right and down moves.

A useful way to practice

Write down what is known and what is only assumed. Look for constraints that eliminate possibilities, then test a small next step. A wrong answer is useful information about the strategy you chose.
