Background
About mental math
Mental math is calculation without external aids — and like typing speed, it is a fluency skill built through short, frequent practice rather than talent. The payoff is everyday: estimating a tip, sanity-checking a spreadsheet, catching a wrong total before it costs money.
Effective practice keeps sessions short and honest. A 60-second sprint with immediate feedback gives your brain dozens of retrieval attempts per session, and tracking your best score makes improvement visible week over week.
These articles cover calculation strategies (left-to-right addition, rounding and adjusting, multiplication shortcuts) and how to fold a one-minute math habit into your day.

FAQ
Common questions about mental math
Why is mental math still useful with calculators everywhere?
Because estimation is a reasonableness check. Catching a misplaced decimal in a bill, budget, or spreadsheet requires a feel for numbers that only fluency provides — and it keeps working memory sharp.
What should I practice first?
Addition and subtraction fluency, then multiplication tables, then percentage tricks. A 60-second daily sprint with immediate feedback covers all of it without needing a study plan.
