Does this number belong to the set of whole numbers? Usually, ground level is considered as height zero.The opposite of an integer is obtained by changing its sign. (a) The opposite of `-3` is `3` and (b) The opposite of `4` is ` -4`. We can change the subtraction into a more familiar addition by realising that subtracting an integer is the same as adding its opposite.Notice that opposite is not the same as absolute value. (a) ` -2 5` means "start at `-2` and go `5` in the positive direction" So we have: It is -4° and snowing. (a) ` -4 - (-3) = -4 ( 3) = -1 ` (We added 3 because the opposite of -3 is 3.) (b) `5 - ( 7) = 5 (-7) = -2.` (We added -7 because the opposite of 7 is -7.The tools devised for such a proof might pry open the logic of the problem, or apply to other Diophantine equations.Results like Booker’s for 33 offer support for this conjecture, giving number theorists more confidence that it’s a proof worth pursuing.For instance, no mathematical method exists that can reliably tell whether any given Diophantine equation has solutions.According to Booker, the sum-of-three-cubes problem “is one of the simplest” of these thorny Diophantine equations.What’s more, Booker and other experts say, each new solution found for one of these holdouts sheds no theoretical light on where, or how, to find the next one.“I don’t think these are sufficiently interesting research goals in their own right to justify large amounts of money to arbitrarily hog a supercomputer,” Booker said. What is “sufficiently interesting,” Booker explained, is that each newfound solution is “a tool for helping you decide what’s true” about the sum-of-three-cubes problem itself.(He says he thought it would take six months, but a solution “popped out before I expected it.”) When the news of his solution hit the internet earlier this month, fellow number theorists and math enthusiasts were feverish with excitement.According to a Numberphile video about the discovery, Booker himself literally jumped for joy in his office when he found out. Part of it is the sheer difficulty of finding such a solution.
