Algebra.Com's Answer #181527 by actuary(112)![]() ![]() ![]() You can put this solution on YOUR website! The calculation is performed by following the \"order of precedence of operations\". First, do the calculaion inisde of the inner parenthesis, so -2+18=16. so the expression is now 2^3-10*(4-16*3)\r \n" ); document.write( "\n" ); document.write( "Next, multiply 16 times 3 remembering that a negative sign is in fron of the 16.\r \n" ); document.write( "\n" ); document.write( "The expression is now 2^3-10\r \n" ); document.write( "\n" ); document.write( "Now do the calculation inside of the parenthesis, remembering the sign of the answer.\r \n" ); document.write( "\n" ); document.write( "The expression is now 2^3-10*(-44)\r \n" ); document.write( "\n" ); document.write( "Now multiply -10 times -44 (A negative number times a negative number is a positive number. So the expression is now 2^3+440\r \n" ); document.write( "\n" ); document.write( "But 2^3=8\r \n" ); document.write( "\n" ); document.write( "So we now have 8+440 and 8+440 = 448 \n" ); document.write( " |
