Algebra.Com's Answer #7403 by elima(1433)![]() ![]() ![]() You can put this solution on YOUR website! -(-4)+10\r \n" ); document.write( "\n" ); document.write( "-12+[-(-5)]\r \n" ); document.write( "\n" ); document.write( "You need to remember any number in parenthesis has a one outside of it, even though in algebra they never write a 1, you need to remember there is. So when you have; \n" ); document.write( "-(-4) it actually is; \n" ); document.write( "-1(-4) and when you multiply 2 negative numbers, what do you get? \n" ); document.write( "A positive, so it would make that -(-4)= 4 \n" ); document.write( "So the problem actually is; \n" ); document.write( "4+10=14 \n" ); document.write( "Same with the other problem; \n" ); document.write( "[-(-5)] = [-1(-5)]= 2 negatives multiplied together= positive,so the answer: \n" ); document.write( "[-1(-5)]=5 \n" ); document.write( "-12+5=-7; \n" ); document.write( "Also keep in mind the rules: \n" ); document.write( "-*-=+ \n" ); document.write( "+*+=+ \n" ); document.write( "When you multiply the same signs answer is positive. \n" ); document.write( "-*+=- \n" ); document.write( "When you multiply different signs, answer is negative. \n" ); document.write( "With adding; \n" ); document.write( "(+)+(+)=+ \n" ); document.write( "(-)+(-)=- \n" ); document.write( "With subtracting; \n" ); document.write( "If the signs are different, subtract the numbers and KEEP THE SIGN OF THE LARGER NUMBER. \n" ); document.write( "ex.; \n" ); document.write( "-12+5= subtract the numbers= 7, and you keep the sign of the larger number,which is -12, so the answer would be -7 \n" ); document.write( "I really hope this clears things up a little. I know negatives and positives get really confusing, but it is SO impoortant to get those! \n" ); document.write( "=) \n" ); document.write( " \n" ); document.write( " |
