🔢 Calculator Hacks You Didn’t Know You Needed
Think calculators are just number-punching bricks of plastic? Think again. The humble calculator has more life hacks packed into it than your average productivity app — and the best part? You don’t need to charge it every night.
Here are five clever ways to get more out of the calculators you think you know, featuring models that are smarter than they look and cheaper than your daily coffee habit.
💰 Hack Your Way to Perfect Pricing
With the Casio DJ-120D This business-ready calculator has a built-in markup (MU) and tax function — but here's the real power move: use it backwards.
Want to find the pre-tax price from a final total? Pop in your total, hit TAX-, and just like that — you’ve reverse-engineered your receipt. It’s like time travel, but for invoices.
🧠 The Memory Trick That Saves Time
With the Sharp EL-334WB Doing repetitive calculations at work or school? The EL-334WB’s memory keys (M+, M-, MR, MC) let you stack numbers like a human spreadsheet.
Hack tip: Use M+ for tallying orders, test scores, or even calories. Come back to it with MR and tally your day in seconds.
🪫 Solar Power: The Original Battery Backup
With the CATIGA CD-8185 Sure, this one’s basic — but its solar panel makes it the ultimate emergency tool. Power out? Phone dead? No worries.
Keep one in your emergency kit or glove box. It’ll outlive most gadgets — and probably your next three smartphones.
🧳 Math on the Move
With the TI-1706SV Pocket Calculator You don’t need a smartphone for math on the fly. This Texas Instruments model is pocket-sized, dual-powered, and built for everyday on-the-go arithmetic.
It even handles square roots and percentages — so yes, it can calculate your tip on that $13.87 lunch.
