negative numbers are easy.\n_|___|___|___|___|___|___|___|___|___|___|_\n-5  -4  -3  -2  -1   0   1   2   3   4   5\n\nthey are the same as positive with simple conversion\n\n1-(-3) same as 1+3\n-1+3 same as 3-1\n\nex.   -8+2-(-10)+(-9)\nfirst you have to make all -(-a) into +a  and all +(-a) into -a\n            -8+2+10-9\nnow split up the negitive numbers and positive numbers and add each seperatly\n           -(8+9)=-(17)   and    +(2+10)=+(12)\nthen subtract the two numbers don't even worry about witch has the neg or pos but remember if the greater one has neg or pos\n          17-12=5\nif the greater number is pos the result is pos\nif the greater number is neg the result is neg\nin this case 17 the greater number is neg so the 5 is neg   (-5)\n\n\nmultiplying/dividing is easier\n\nex.  (-3)*5*(-(3+4))/(-7)*2+3\nstart off by doing all of the adding in the () if a + or - shows up in the middle i will show you how to do that next example\n     (-3)*5*(-7)/(-7)*2\ncount up all the neg number don't count any adding or subtracting\n     (-3)...1   (-7)...2   (-7)...3     3 neg numbers\nif it is an odd number of neg then it is a neg number\nif it is an even number of neg then it is a pos number\nthis one has 3 neg witch is odd so it will result in a neg number\n\nnow do the problem as if all pos\n3*5*7/7*2  15*7/7*2  105/7*2  15*2  30\n\nsence it will result neg it will be -30\n\nex.   3*(-2)+(2+4)-8/4*4-15+(6+3)*5\nnow to show you how to do * and/or / and + and/or -\nfirst do the ()\n     3*(-2)+6-8/4*4-15+9*5\nnow seperate all in between + or -\n     (3*(-2))+(6)-(8/4*4)-(15)+(9*5)\nnext do all of the () in this\n     (-6)+(6)-(8)-(15)+(45)\ntake out all the () but leave in same spots\n     -6+6-8-15+45\nyou know how to do this part from first ex.\n     -(6+8+15)=-29          +(6+45)=+51\n     51-29=22     greater is pos so it is +22\n\nif you still don't get it email me to see your exact problem

Ask Dr. Math is my favorite.  You can also try Mathworld, though I usually find that I leave it more confused than when I entered.
