Solve 666+1div2+4div2-3

$$666+1 \div 2+4 \div 2-3$$

Evaluate

$$\frac{1331}{2}=665.5$$

Solution Steps

Convert 666 to fraction \frac{1332}{2}.

$$\frac{1332}{2}+\frac{1}{2}+\frac{4}{2}-3$$

Since \frac{1332}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$\frac{1332+1}{2}+\frac{4}{2}-3$$

Add 1332 and 1 to get 1333.

$$\frac{1333}{2}+\frac{4}{2}-3$$

Since \frac{1333}{2} and \frac{4}{2} have the same denominator, add them by adding their numerators.

$$\frac{1333+4}{2}-3$$

Add 1333 and 4 to get 1337.

$$\frac{1337}{2}-3$$

Convert 3 to fraction \frac{6}{2}.

$$\frac{1337}{2}-\frac{6}{2}$$

Since \frac{1337}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1337-6}{2}$$

Subtract 6 from 1337 to get 1331.

$$\frac{1331}{2}$$

Factor

$$\frac{11 ^ {3}}{2} = 665\frac{1}{2} = 665.5$$
