Answer 2

1. 7 × 6 × 5 × 4 × 3 × 2

= 42 × 5 × 4 × 3 × 2

= 210 × 4 × 3 × 2

= 840 × 3 × 2

= 2.520 × 2

= 5.040

2. 7! + 3!

= ( 7 × 6 × 5 × 4 × 3 × 2 ) + ( 3 × 2 × 1 )

= ( 42 × 5 × 4 × 3 × 2 ) + ( 6 × 1 )

= ( 210 × 4 × 3 × 2) + 6

= ( 840 × 3 × 2 ) + 6

= ( 2.520 × 2 ) + 6

= 5.040 + 6

= 5.046

3. ½ + ¼ =

../4 + ¼

= (4 ÷ 2 × 1)/4 + ¼

= 2/4 + ¼

= ¾
