Understand how a tool works before you use its result. These guides explain the method, show an example where it helps, and call out the limits worth checking.
Start with a question, read the explanation, then open the related live tool when you are ready to apply it.
Check the worked example and assumptions before applying a result. Where rates or product rules vary, follow the current source linked in the guide.
A direct static QR code stores its destination in the symbol, so FivoTools does not impose an expiration date. The destination can still change or disappear, and a damaged print may become hard to scan. Learn how that differs from a redirect-based code.
An overnight shift crosses midnight, so a simple clock-time subtraction can produce the wrong total. Follow an example that accounts for the date boundary, unpaid breaks, and decimal hours, then check which pay rules apply to your situation.
A raise can be quoted as a percentage, a flat amount or a new pay figure. See how all three describe the same change, why the old pay is the percentage baseline, and what an hourly raise means in annual gross pay.
An hourly equivalent depends on the hours and paid weeks you assume. Compare offers on the same gross-pay basis, then check benefits, overtime and other terms that a simple conversion leaves out.
Markup measures gross profit against cost; margin measures it against selling price. See both formulas using the same worked example and learn why using the wrong percentage can change a target price.
A 6:12 pitch means six units of rise over twelve units of horizontal run. Learn how that ratio relates to slope angle and sloped-area estimates, and why product-specific roofing requirements still need a separate check.
A roof’s flat footprint is smaller than its sloped surface. Follow the pitch multiplier and overhang example, then learn when a complex roof needs separate measurements.
The same deck area can need different board counts. Work through actual width, gaps, running direction, stock length and waste before treating a planning estimate as an order.
A useful result needs context. Our guides connect a tool's inputs and formulas to practical examples, and distinguish general explanations from rules or product requirements that may vary. See how we choose sources and handle corrections.
