Algebra.Com's Answer #249708 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! In order for the sum of all these integers to be a positive 26 we must have enough positive integers to cancel out all the negative integers plus enough other positive integers to add up to 26. With a like thought we will realize that \n" ); document.write( "1 will cancel out -1 \n" ); document.write( "2 will cancel out -2 \n" ); document.write( "3 will cancel out -3 \n" ); document.write( "etc. \n" ); document.write( "25 will cancel out -25 \n" ); document.write( "So the consecutive integers from -25 to 25 will add up to zero! The next integer, 26, will bring the grand total up to 26! \n" ); document.write( "So to get a sum of 26 we have \n" ); document.write( "-25 to -1: 25 integers \n" ); document.write( "1 to 26: 26 integers \n" ); document.write( "and don't forget 0: 1 integer. \n" ); document.write( "This makes a total of 52 consecutive integers from -25 to 26. \n" ); document.write( " |
