Max and Ruby's trail
Hi friend! Meet two puppies, Max and Ruby. They're on a trail with mile signs. Max is at mile 51. Ruby is at mile 57. How far apart are they? Let's find out!
Count the hops
Here's the trail. Max is at 51. Ruby is at 57. Count the hops from Max to Ruby: one, two, three, four, five, six. They are 6 apart! And 57 − 51 = 6 too.
Let's solve 62 and 48
Max is at 62. Ruby is at 48. Start at the smaller number, 48. Hop 2 to reach 50. Then hop 12 to reach 62. 2 + 12 = 14. They're 14 apart. Don't add 62 and 48!
