|[3,2],[4,5]|=3times square-square times4quad =square-8=square

Fill in the blanks with correct number. |{:(3,2),(4,5):}|=3xxsquare-squarexx4 =square-8 =square

Rationalize the denominator: 4/\sqrt{5} = 4/\sqrt{5} times square/square = (4square)/square .

Complete the following: 2x+y=8 x: 0, square , 3 y: square , 4, 2 (x,y): square , square , (3,2) x-y=1 x: square , 2, square y: -1, square , 4 (x,y): square , square , square

Let's calculate mentally. 7 xx 33 = 7 xx (square+square)=7 xx square+ 7 xx square = square + square = square

Let's calculate mentally. 9 xx 98 = 9 xx (100-2) = square xx square - square xx square = square
