\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?

Algebra.Com's Answer #68671 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 4 - 4^2 divided by 8 x 3 + 6 \n" ); document.write( "----------- \n" ); document.write( "Is this your problem? \n" ); document.write( "4-16/8*3+6 \n" ); document.write( "=4-2*3+6 \n" ); document.write( "=4-6+6 \n" ); document.write( "=4 \n" ); document.write( "----------- \n" ); document.write( "OR is this your problem? \n" ); document.write( "[4-4^2]/[8*3+6] \n" ); document.write( "= -12/30 \n" ); document.write( "= -2/5 \n" ); document.write( "---------------- \n" ); document.write( "Comment: When you write \"divided by\" the reader cannot \n" ); document.write( "tell where the denominator ends.
