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." } ], "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%." } ], "inflation": [ { "question": "What does the Inflation Calculator estimate?", "answer": "Estimate future cost and purchasing power after inflation." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "paycheck": [ { "question": "What does the Paycheck Calculator estimate?", "answer": "Estimate gross pay, taxes, deductions, and take-home pay." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "cost-of-living": [ { "question": "What does the Cost of Living Calculator estimate?", "answer": "Compare monthly budgets and estimate income needed for a new cost level." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "refinance": [ { "question": "What does the Mortgage Refinance Calculator estimate?", "answer": "Compare current and refinance mortgage payments, savings, and break-even time." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "rent-vs-buy": [ { "question": "What does the Rent vs Buy Calculator estimate?", "answer": "Compare five-year renting costs with estimated buying costs." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "retirement": [ { "question": "What does the Retirement Calculator estimate?", "answer": "Project retirement savings from age, savings, contributions, and return." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "investment-return": [ { "question": "What does the Investment Return Calculator estimate?", "answer": "Calculate net return, total return rate, and annualized return." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "debt-payoff": [ { "question": "What does the Debt Payoff Calculator estimate?", "answer": "Estimate payoff time, total interest, and total paid for a debt." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "credit-card-payoff": [ { "question": "What does the Credit Card Payoff Calculator estimate?", "answer": "Estimate credit card payoff time and interest with extra payments." }, { "question": "What can change the estimate?", "answer": "This is an estimate, so taxes, fees, payment timing, compounding, and changing returns can move the result." } ], "right-triangle": [ { "question": "What formula does the Right Triangle Calculator use?", "answer": "c = ?(a^2 + b^2), area = a x b / 2." } ], "percentage": [ { "question": "What formula does the Percentage Calculator use?", "answer": "Percent of value = value × percent / 100.

Increase or decrease = value × (1 ± percent / 100)." }, { "question": "How do you calculate a percentage increase?", "answer": "To calculate a percentage increase, subtract the original value from the new value to find the absolute difference. Then, divide that absolute difference by the original value and multiply the result by 100." }, { "question": "Is a 50% increase followed by a 50% decrease the same original number?", "answer": "No. If you increase $100 by 50%, you get $150. If you then decrease that $150 by 50%, you lose $75, leaving you with $75.

The 'median' is the middle number when the data is sorted from lowest to highest. The 'mode' is the number that appears most frequently in the dataset." }, { "question": "How do outliers affect an average calculation?", "answer": "The mean (standard average) is highly sensitive to extreme outliers. A single massive number can skew the average significantly higher. In datasets with extreme outliers, the median is often a more accurate representation of a 'typical' value." } ], "speed-distance-time": [ { "question": "What formula does the Speed Distance Time Calculator use?", "answer": "v = d / t, where speed equals distance divided by time." }, { "question": "What is the formula to calculate speed?", "answer": "Speed is mathematically calculated by dividing the total distance traveled by the total time it took to travel that distance (Speed = Distance ÷ Time)." } ], "force-mass-acceleration": [ { "question": "What formula does the Newton's Second Law Calculator use?", "answer": "F = m x a." } ], "kinetic-energy": [ { "question": "What formula does the Kinetic Energy Calculator use?", "answer": "KE = 0.5 x m x v^2." } ], "ohms-law": [ { "question": "What formula does the Ohm's Law Calculator use?", "answer": "V = I x R.
