\n" );
document.write( "I know you do order of operations, but I do not know if it matters if I multiply or divide first after I get the exponent.\r
\n" );
document.write( "\n" );
document.write( "4 - 4^2 divided by 8 x 3 + 6\r
\n" );
document.write( "\n" );
document.write( "What I did was get 4 -16 divided by 8 x 3 + 6
\n" );
document.write( "Then if I multiplied first, I would get 4 - 16 divided by 24 + 6
\n" );
document.write( "Then I would get 4 - 2/3 + 6. Then I'd get 9 and 1/3.
\n" );
document.write( "On my calculator I got 4, but that would only work if I divided before I multiplied. I know division and multiplication are inverse opperations, so would it be okay if I divided first and got 4 as the answer?
\n" );
document.write( "Thanks. \n" );

Algebra.Com's Answer #68681 by edjones(8007)![]() ![]() You can put this solution on YOUR website! Tip #1 don't use x for a times sign. Use * \n" ); document.write( "then you wont get the x's in your problems mixed up with your times signs. \n" ); document.write( "Tip #2 use brackets ( ) or [ ] etc. to avoid confusion. Eg: 8*3+6 could be 8(3+6). \n" ); document.write( "Whether you do multipliction or division 1st doesn't make any difference but the way you set up the problem does. \n" ); document.write( "If you want to divide 1st (4-16)/((8*3)+6)) is the way to set it up. \n" ); document.write( "the calculator will give -0.4 as the answer. \n" ); document.write( "With pencil and paper we do the operations inside the brackets 1st. \n" ); document.write( "(4-16)=-12 \n" ); document.write( "(8*3)=24 \n" ); document.write( "(24+6)=30 \n" ); document.write( "-12/30=-0.4 \n" ); document.write( "EdJones \n" ); document.write( " \n" ); document.write( " |
