Evaluate

$$155$$

Solution Steps

Multiply 18 and 31 to get 558.

$$\frac{558\times 18\times 31-8\times 31\times 8\times 31}{26\times 62}$$

Multiply 558 and 18 to get 10044.

$$\frac{10044\times 31-8\times 31\times 8\times 31}{26\times 62}$$

Multiply 10044 and 31 to get 311364.

$$\frac{311364-8\times 31\times 8\times 31}{26\times 62}$$

Multiply 8 and 31 to get 248.

$$\frac{311364-248\times 8\times 31}{26\times 62}$$

Multiply 248 and 8 to get 1984.

$$\frac{311364-1984\times 31}{26\times 62}$$

Multiply 1984 and 31 to get 61504.

$$\frac{311364-61504}{26\times 62}$$

Subtract 61504 from 311364 to get 249860.

$$\frac{249860}{26\times 62}$$

Multiply 26 and 62 to get 1612.

$$\frac{249860}{1612}$$
