I am studying for the SAT and one of the sample problems is:
\n" ); document.write( "For all numbers x and y, let x (they have a triangle drawn between x and y. I do not know what the triangle means)y be defined as x triangle y = x squared + xy + y squared. What is the value of (3 triangle 1) triangle 1? \r
\n" ); document.write( "\n" ); document.write( "The triangle is defining a mathematical operation to be performed
\n" ); document.write( "on x and y.
\n" ); document.write( "You are told:
\n" ); document.write( "x T y= x^2+xy+y^2\r
\n" ); document.write( "\n" ); document.write( "You are then asked to evaluate (3 T 1)T 1
\n" ); document.write( "The 3T1= 3^2+3*1+1^2 = 9+3+1=13
\n" ); document.write( "Then 13 T 1 = 13^2 + 13*1 + 1^2 = 169 +13+1 = 30
\n" ); document.write( "Hope this helps.
