How To Do Math In Your Head!

If you want to get better at math or do it faster in your head, so you can do better at work or do better in school, there’s a way to do so.

One of the things my Dad taught me early on was to do math in my head, whenever I could.  He taught me to round things to 10′s, 100′s, 1000′s, and to re-arrange the math and break it down if it was, too complex.

This helps, whether you’re doing math in your head, or doing some quick figures on paper, or even using a calculator.

If you can do quick math estimates in your head, it gives you an advantage at work when people are throwing numbers around.  This can help you quickly get a sense of how many, how much, how often, or what percent, when people are throwing numbers you way.

It can also help you in interviews under pressure, or it can help you day-to-day to get a rough idea of how much you are spending at the store.

More importantly, if you can quickly get to ballpark estimate and make meaning out of numbers, you can focus on the bigger context, or play out “what if” scenarios, rather than get distracted, or lose the flow, while you pull out calculators or number crunch. And, in a lot of scenarios, not everybody is going to wait for you to pull out a calculator, … or catch up.

But how do you do math in your head?
