Solve {l}{9101/2}{-81/2}{10/2}

$$\left. \begin{array} { l } { 910 \frac { 1 } { 2 } } \\ { - 8 \frac { 1 } { 2 } } \\ { 1 \frac { 0 } { 2 } } \end{array} \right.$$

Evaluate

$$901$$

Solution Steps

Multiply 910 and 2 to get 1820.

$$\frac{1820+1}{2}-\frac{8\times 2+1}{2}-\frac{1\times 2+0}{2}$$

Add 1820 and 1 to get 1821.

$$\frac{1821}{2}-\frac{8\times 2+1}{2}-\frac{1\times 2+0}{2}$$

Multiply 8 and 2 to get 16.

$$\frac{1821}{2}-\frac{16+1}{2}-\frac{1\times 2+0}{2}$$

Add 16 and 1 to get 17.

$$\frac{1821}{2}-\frac{17}{2}-\frac{1\times 2+0}{2}$$

Since \frac{1821}{2} and \frac{17}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1821-17}{2}-\frac{1\times 2+0}{2}$$

Subtract 17 from 1821 to get 1804.

$$\frac{1804}{2}-\frac{1\times 2+0}{2}$$

Divide 1804 by 2 to get 902.

$$902-\frac{1\times 2+0}{2}$$

Multiply 1 and 2 to get 2.

$$902-\frac{2+0}{2}$$

Add 2 and 0 to get 2.

$$902-\frac{2}{2}$$

Divide 2 by 2 to get 1.

$$902-1$$

Subtract 1 from 902 to get 901.

$$901$$

Factor

$$17\times 53$$
