The day the Soviets officially crossed the border, I wrote to President Carter: We now have the opportunity of giving to the USSR its Vietnam War..  Afghanistan, then, in a sense, became the United States' pawn.
There is no largest number. One simple way to consider this is to  look at the function:    f(x) = x + 1    Pick any number, and plug it into that function. No â¦ matter what  number you plug in, the function will always give you a number that  is one larger than the previous one. It doesn't matter how big x  is, there will always be an x + 1 value, which will always be  larger than x.
12 is an abundant number, and this is because the sum of its proper divisors (1, 2, 3, 4, 6) is larger than 12. It can be shown by trial and error that 12 is the first abundant number (i.e. there are no abundant numbers smaller than 12). The following is the list of the first 22 abundant numbers: 12, 18, 20, 24, 30, 36, 40, 42, 48, 54, 56, 60, 66, 70, 72, 78, 80, 84, 88, 90, 96, 100. In fact, the first 60 abundant numbers are all even numbers! But this does not mean that all abundant numbers are even numbers. Can you find the first odd abundant number?
