\"[\" this is the bracket
\n" ); document.write( "it works like a parentheses
\n" ); document.write( "the parentheses indicates priority in a equation
\n" ); document.write( "the numbers that are inside it need be solved first
\n" ); document.write( "the bracket comes after of the parentheses
\n" ); document.write( "so first you solve the parentheses and later the bracket
\n" ); document.write( "4[3(21-17)+3]
\n" ); document.write( "4[3(4)+3]
\n" ); document.write( "4[3*4+3]
\n" ); document.write( "4[12+3]
\n" ); document.write( "4[15]
\n" ); document.write( "4*15
\n" ); document.write( "60
\n" ); document.write( "and after of the braket still exist the \"{\" it is the third and last to be solved \n" ); document.write( "

\n" );
