Getting Help from the Numbers

Have you ever noticed that it’s socially acceptable to be afraid of math? Most of us don’t bat an eye when someone says, “I can’t do math.” Actually, we all do math every day and don’t even think about it-whether it’s figuring how long it will take you to run an errand (speed and distance) or how much to leave as a tip in a restaurant (fractions). Sometimes, a little extra math can help guide an investigation and help you figure out whether you’re looking at a typical situation or something that “just doesn’t look right.” Don’t be afraid of math-math can be your savior!
