Fill in the chart for Letter A.

• 50 x (200 + 36)

  = 11,800

• 50 x (64 + 36)

  = 5,000

• 64 x (50 + 36)

  = 5,504

• 36 x (64 + 50)

  = 4,104

• e. 10 × (250 + 45)

Fill in the chart for letter B.

• 15 times the sum of 14 and 6

  = 300

• (1,200 - 5) / 700

  = 1.707

• c. (1,200 - 700) / 5

  = 100

• (700 - 5) / 1,200

  = 0.5792

• e. 10 × (250 + 45)

  = 2,950

Multiply using the standard algorithm.

• = 16962
