 If 45% of an item is 90.00 2019-05-01 Gavin pose la question :If 45% of an item is 90.00 what is the original price?Penny Nom lui répond. 0123456789 2009-03-25 Dr. pose la question :Many years ago I discovered that there are 33 numbers which, when multiplied by 0123456789, simply rearrange the digits. Surprisingly (to me at least) is the fact that the digits of all of those 33 numbers add up to one of the 6 "cardinal" numbers 1, 2, 4, 5, 7, and 8. For example 6 + 2 = 8 and 62 X 0123456789 = 7654320918 etc. Another interesting (to me) fact is that only the cardinal numbers 1, 2, 4, 5, 7, and 8 rearrange the digits in the number 9876543210. My question is: "Is this known to anyone but me and the people I have told?"Robert Dawson lui répond.
