WIKI TALK with PROFESSIONALS (Useful, Actual, Realistic & Relevant, but Unanswered):

"Hi. I have reverted your edit on mathematical finance. I am unclear as to why you view "mathematical finance" and "financial mathematics" as separate subjects. Citations would be needed to backup such a change." Zfeinst (talk) [I'm a professor at Stevens Institute of Technology, having obtained my PhD in financial engineering from Princeton University, 1)Member of WikiProject Finance & Investment, 2)Member of WikiProject Economics, 3)Member of Business WikiProject, 4)Member of WikiProject Mathematics, 5)Member of WikiProject Systems, etc.] 14:54, 28 August 2022 (UTC)[ reply]:

(I):Unfortunately the burden of logic (not just citation) is not on my side, Sir: Professor, are you honestly believe that MATHFIN=FINMATH ???


 * 1)Most of the people -except very few mathematician- think that MathFin is different than FinMath, as Production House >< House Production, Business Computer >< Computer Business, House Dog >< Dog House, etc. 2)By Common Law, MathFin [not FinMath] are Finance guy, punishable if not following the non-mathematical social consensus "IFRS, GAAP, Basel, Lex-US, Lex-Euro, Dual Entry, Accrual, Deferral, CAR, LDR, LLL, Depreciation, Tax, Deductibles, etc". 3)MathFin [not FinMath] is very-very important in actual real business' computer programming!! 4)So please the minority give proof to the majority that MathFin=FinMath !!!, 5)Thanks.

(II):Please solve the most common legal MATHFIN [not FinMath] case, non numerical Pacioli's "geometria" & "proportionalita" (I'll tell you the answer, if you could not solve):


 * "State the financial proforma (Balance-sheet & Income Statement at IFRS-GAAP standard) to be signed by Owners & CEO+CFO in the Annual Shareholders Meeting, with the known Last Year's Revenue and this year's Revenue, Variable Cost, Interest Expense, Before Tax Income, After Tax Income, Net Dividend, Retained Earnings, Total Assets, Capital, Long-term Debt, Account Payable, Kind of Cash, Inventory and Account Receivable, at legal Income & Dividend Tax Rate with 5% improvements of all driving ratios (Sales Growth, Variable Portion, Fixed Portion, Interest Portion, Dividend Payout, Leverage, Days Payable, Days Receivable, Days Inventory, Current Ratio & Quick Ratio)."

(III}:Also another common non numerical MATHFIN [not FinMath] case of 3 companies merger, "summa arithmetica, geometria, proportioni & proportionalita", not just easier than the case before, but also easier than 4 companies acquisition (I explain you the solution, if you could not tell them):


 * "In case of 3 different companies merger: F, G, H (i.e Fedex, General Motors & Hilton), please give the 30 finance ratio formulas after merger: 01)Asset to debt, 02)Debt to capital, 03)Capital to revenue, 04)Revenue to expense, 05)Expense to earnings, 06)Earnings to asset, 07)Asset to capital, 08)Debt to revenue, 09)Capital to expense, 10)Revenue to earnings, 11)Expense to asset, 12)Earnings to debt, 13)Asset to revenue, 14)Debt to expense, 15)Capital to earnings, 16)Revenue to asset, 17)Expense to debt, 18)Earnings to capital, 19)Asset to expense, 20)Debt to earnings, 21)Capital to asset, 22)Revenue to debt, 23)Expense to capital, 24)Earnings to revenue, 25)Asset to earnings, 26)Debt to asset, 27)Capital to debt, 28)Revenue to capital, 29)Expense to revenue and 30)Earnings to expense."

(IV)Please solve the banker's daily MATHFIN [not FinMath] non numerical Financing, "Smith" vs "Cobb-Douglas" (I could explain you the answer, if you do not know how to do it):


 * "1)How much money needed to financing the optimum business if given the time series data of Quantity, Price and Total Cost? 2)How big is the optimum total sales? 3)How much its total cost? 4)How big its total profit? 5)What is its selling price per unit? 6)Cost per unit? 7)Profit per unit? 8)How many unit sold at its optimum? 9)What is its average variable cost? 10)Its average fixed cost?, 11)Its total variable cost?, 12)Its total fix cost? 13)Where is its shut-down point? Also explain the differences if the company is 'dominant' or in a 'competitive' free market?" Hanshifu+62 (talk) 04:47, 31 August 2022 (UTC)
