Is chasing a lapsed customer worth it? The win-back math
2026-09-24 · 3 min read

A win-back campaign is only worth running if the profit that customer represents beats what the campaign costs to send — five numbers and two multiplications settle it either way.

Converting length units: the method behind meters, miles and feet
2026-09-24 · 2 min read

Every length conversion is one multiplication once you know a unit's factor in meters — the trick is picking exact factors, not rounded ones, so the answer doesn't quietly drift.

Comparing two loan offers: total cost beats monthly payment
2026-09-14 · 3 min read

The offer with the lower monthly payment can still cost more overall once you multiply by the term and add the fees — the fix is one formula and a habit of comparing totals, not payments.

Home insurance coinsurance: what being underinsured actually costs
2026-09-14 · 3 min read

A property policy can cut a claim payout — not just cap it — if you're insured below the coinsurance percentage the policy requires, and checking is one formula you can run before a loss happens.

How much paint you need: the gallons and labor math
2026-09-13 · 2 min read

Paint coverage on the can only tells you gallons per coat — multiply by coats, divide by coverage, round up to a whole can, then add labor for the real total.

Bankruptcy exemptions: what property you actually keep
2026-09-13 · 3 min read

Federal law protects a set dollar amount of home equity, a vehicle, household goods and more in bankruptcy — and a wildcard exemption that grows the less home equity you have.

ARM payment shock: what your mortgage payment becomes at reset
2026-09-12 · 2 min read

An adjustable-rate mortgage doesn't just change its rate at reset — it re-amortizes the whole remaining balance at that rate, which is why a modest rate move can turn into a much bigger payment jump.

Factorial: the multiplication behind every possible order
2026-09-12 · 2 min read

n! multiplies every whole number from n down to 1, and it answers a simple question — how many ways can these things be arranged — that shows up in probability, lottery odds and combinatorics.

Logarithms: the one formula behind pH, decibels and bits
2026-09-12 · 2 min read

A logarithm just asks “what power gets me here” — pH, decibel and bit-count problems all reduce to that one question, and the change-of-base rule handles any base a calculator doesn't have a button for.

Line slope: the formula behind ramps, roofs and road grade
2026-09-12 · 2 min read

Slope is just rise over run — but from two points you also get the angle and the y-intercept for free, and a wheelchair ramp, a roof pitch and a road survey all use the same three numbers.

Volume of shapes: four formulas for box, cylinder, sphere and cone
2026-09-11 · 2 min read

Every volume formula here reduces to the same idea — base area times height, adjusted for the shape — and a shipping box worked two ways is the fastest way to see why the adjustment matters.

Powers and roots: the same formula running both directions
2026-09-11 · 2 min read

An exponent says multiply a number by itself repeatedly; a root undoes that — and a fractional exponent is both operations at once, which is worth being able to do on paper before trusting a calculator's display.
