Then, hit start and begin work on your first task. Take short and long breaks as guided by the timer. You can hit the skip button to finish early.

These detected conditions feed into XOR gates, which decide whether each flip-flop should flip or stay the same on the next tick. This separation is important: AND gates detect when a carry should happen, and XOR gates apply that carry by flipping the bit. Additional MOD logic watches the four stored bits and generates a reset pulse when the digit reaches an invalid value (such as 10 or 6).

In the early years of a 30-year mortgage, the vast majority of your payment goes toward paying off interest. Over time, the balance shifts, and your final years of payments are applied almost entirely to the principal balance." }, { "question": "What is the difference between an interest rate and an APR?", "answer": "The interest rate is the base cost of borrowing the principal loan amount. The Annual Percentage Rate (APR) is a broader measure that includes the interest rate plus broker fees, discount points, and closing costs, revealing the true total annual cost of the mortgage." } ], "apr": [ { "question": "What does the APR Calculator estimate?", "answer": "Estimate annual percentage rate from finance charges and loan term." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." }, { "question": "What does APR stand for on a credit card?", "answer": "APR stands for Annual Percentage Rate.

APY (Annual Percentage Yield) is the interest you earn when you save or invest money, such as in a high-yield savings account, and it factors in the effects of compound interest." } ], "amortization": [ { "question": "What does the Amortization Calculator estimate?", "answer": "Estimate payment, remaining balance, and principal paid for an amortized loan." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "budget": [ { "question": "What does the Budget Calculator estimate?", "answer": "Compare monthly income against common expense categories." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "car-loan": [ { "question": "What does the Car Loan Calculator estimate?", "answer": "Estimate an auto loan payment with taxes, fees, down payment, and trade-in." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." }, { "question": "Should I choose a 60-month or 72-month auto loan?", "answer": "A 72-month loan will give you a lower monthly payment, but you will pay significantly more in total interest over the life of the loan. Additionally, longer terms increase the risk of becoming 'upside down' on the loan, where you owe more than the car is currently worth due to rapid vehicle depreciation." }, { "question": "Does my trade-in value reduce my car loan interest?", "answer": "Yes. Applying a trade-in value or a cash down payment directly reduces the total principal amount you need to finance. Because auto loan interest is calculated based on the principal balance, lowering the principal reduces the total interest paid over the life of the loan." } ], "compound-interest": [ { "question": "What does the Compound Interest Calculator estimate?", "answer": "Project savings or investment growth with monthly contributions." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." }, { "question": "What is the Rule of 72 in compound interest?", "answer": "The Rule of 72 is a mental math shortcut to estimate how long it takes to double an investment. Divide 72 by your annual compound interest rate. For example, at an 8% interest rate, your money will double in approximately 9 years (72 ÷ 8 = 9)." }, { "question": "How does compounding frequency affect total returns?", "answer": "The more frequently interest is compounded, the faster your money grows. Daily compounding yields slightly more than monthly compounding, and monthly yields more than annual, because the interest you earn begins generating its own interest sooner." } ], "simple-interest": [ { "question": "What does the Simple Interest Calculator estimate?", "answer": "Calculate interest and total amount with a fixed-rate simple interest formula." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "savings-goal": [ { "question": "What does the Savings Goal Calculator estimate?", "answer": "Estimate how long it will take to reach a savings target." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "solar-panel-cleaning": [ { "question": "How much electricity does a typical solar panel system produce?", "answer": "Energy production varies by geographic location, shading, and equipment efficiency, but a standard residential system generates roughly 4.5 peak kilowatt-hours (kWh) per day per kilowatt (kW) of installed capacity under full sun." }, { "question": "What is a realistic number for annual dust and soiling loss?", "answer": "For most suburban environments with regular seasonal rainfall, an annual efficiency loss of 5% to 7% is standard. If you live in an arid, desert climate, near heavy agricultural dust, or downwind from active construction, your losses can climb to 10% or even 20%." }, { "question": "Does rain completely replace the need for manual cleaning?", "answer": "While light rain clears away loose dust, it does not remove heavier materials like baked-on bird droppings, sticky tree sap, or industrial film. If these stubborn elements are left on the panels, they continue to cause localized efficiency drops even after a rainstorm." }, { "question": "Where can I find my current electricity rate?", "answer": "Your electricity rate can be found directly on your recent utility bill, usually listed as the cost per kilowatt-hour ($/kWh). If your utility relies on complex Time-of-Use (TOU) or tiered pricing, using your average off-peak or mid-peak rate is a reliable baseline for this calculation." } ], "tip": [ { "question": "What does the Tip Calculator estimate?", "answer": "Calculate a tip, total bill, and split amount per person." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." }, { "question": "Do you calculate a tip on the pre-tax or post-tax amount?", "answer": "Standard etiquette dictates calculating your tip based on the pre-tax subtotal. Tipping on the post-tax amount means you are tipping the server on the government's sales tax, which artificially inflates the gratuity." }, { "question": "How can I quickly estimate a 15% tip?", "answer": "Find 10% of the bill by moving the decimal one spot to the left. Then, find half of that amount (which equals 5%). Add those two numbers together to get exactly 15%." } ], "moneyline-to-implied-probability": [ { "question": "How do I convert moneyline odds to implied probability?", "answer": "Yes. Enter the moneylines, and the calculator shows the raw implied chance, the adjusted chance after removing the market margin, and the house edge." }, { "question": "How do I calculate the implied chance for for win, loss, or draw given a moneyline?", "answer": "Let's say you have betting odds of -300 for one team, +400 for a draw, and +800 for the other team. Yes, you can calculate the implied chance for each event. American odds use two formulas because favorites and underdogs are written differently. Negative odds use abs(odds) / (abs(odds) + 100), and positive odds use 100 / (odds + 100). For -300, 300 / 400 = 0.75, or 75.00%. For +400, 100 / 500 = 0.20, or 20.00%. For +800, 100 / 900 = 0.1111..., or 11.11%. Add the raw probabilities together and you get 106.11%. The extra 6.11% is the vig, juice, or overround. To remove it, divide each raw probability by 106.11%.

Simple only backslashes the usual regex metacharacters, so the result is shorter and easier to read." }, { "question": "Why does RegExp.escape() treat the first character differently?", "answer": "RegExp.escape() can hex-escape a leading letter or digit so the escaped text cannot accidentally join with text that already comes before it in a larger pattern." } ], "diff-checker": [ { "question": "What does Diff Checker help inspect or debug?", "answer": "Compare two blocks of text line by line." }, { "question": "Can I copy or export the result from Diff Checker?", "answer": "Yes.
