It’s hard to believe how many adults can not add or subtract at even the most basic level because these are skills that most of us use every day, particularly if you sell fruit for a living. Moreover rather than put forth a tiny effort to improve basic math skills by not relying on a calculator for everything, and I mean everything, it seems most people prefer to reach for the calculator. I’m not talking about for double digit multiplication but for things like: something cost 60, I give you 100, how much should I get back. I encourage you to and to encourage others to use their brains and bodies more. Getting in the habit of doing basic math in your head is a good place to start. Just because someone has a calculator don’t expect them to do the math for you and instead see if your brain can beat their fingers to the result.
