2A = 4²

2A = 16

A  = 16 ÷ 2

A  = 8

 

B = A − 3

B = 8 − 3

B = 5

 

G = B + 1

G = 5 + 1

G = 6

 

A² × ½ + B! − (−G!) = ?

= 8² × ½ + 5! − (−6!)

= 64 × ½ + 5! − (−6!)

= 64 ÷ 2 + 5! − (−6!)

= 32 + 5! − (−6!)

 

5! = 5 × 4 × 3 × 2 × 1

   = 20 × 3 × 2 × 1

   = 60 × 2 × 1

   = 120 × 1

   = 120

 

6! = 6 × 5 × 4 × 3 × 2 × 1

   = 30 × 4 × 3 × 2 × 1

   = 120 × 3 × 2 × 1

   = 360 × 2 × 1

   = 720 × 1

   = 720

 

A² × ½ + B! − (−G!)

= 32 + 120 − (−720)

= 32 + 120 + 720

= 152 + 720

= 872

 

∴  A² × ½ + B! − (−G!) = 872
