Who needs a calculator when you’ve got a dog?
Beau, a 12-year-old Labrador retriever, can help you solve all your math problems. What’s the square root of 9? Ask him, and he’ll tell you in barks – even if his owner, Dave Madsen, isn’t nearby.
Madsen, of Missoula, Mont., started teaching his intelligent dog how to count when Beau was a puppy, and now Beau can answer a variety of complicated questions involving addition, subtraction, division, multiplication and more.
