word problem/find a number	repeated subtraction	מלאכת_המספר#TEa8	Question: if we subtract 12 from the double of any number, then we subtract another 12 from double the remainder also, and double the remainder is 12, how much is the original number? :$\scriptstyle2\sdot\left[\left[2\sdot\left(2X-12\right)\right]-12\right]=12$ שאילה אם מכפלו של אי זה מספר נקח י"ב ומכפל הנשאר נקח ג"כ י"ב אחרי' וכפל הנשאר יהיה י"ב כמה היה המספר הראשון
word problem/find a number	repeated subtraction	ספר_חשבון#QPoG	A number, you subtract a tenth from it, then you subtract again a tenth from the remainder, and 100 are left. :How much was the original number before subtracting the two tenths? :$\scriptstyle X-\frac{1}{10}X-\left[\frac{1}{10}\sdot\left(X-\frac{1}{10}X\right)\right]=100$ אם ישאלך אדם חשבון שהסרות ממנו הי' ומן הנשאר הסרות ממנו העשירית פעם שנית ונשארו ק‫' כמה היה כל החשבון בטרם שהסרת ממנו ב' העשיריות
