Solve 4*9-4*4div2-3*9div2-5div2=

$$4 \times 9-4 \times 4 \div 2-3 \times 9 \div 2-5 \div 2=$$

Evaluate

$$12$$

Solution Steps

Multiply 4 and 9 to get 36.

$$36-\frac{4\times 4}{2}-\frac{3\times 9}{2}-\frac{5}{2}$$

Multiply 4 and 4 to get 16.

$$36-\frac{16}{2}-\frac{3\times 9}{2}-\frac{5}{2}$$

Divide 16 by 2 to get 8.

$$36-8-\frac{3\times 9}{2}-\frac{5}{2}$$

Subtract 8 from 36 to get 28.

$$28-\frac{3\times 9}{2}-\frac{5}{2}$$

Multiply 3 and 9 to get 27.

$$28-\frac{27}{2}-\frac{5}{2}$$

Convert 28 to fraction \frac{56}{2}.

$$\frac{56}{2}-\frac{27}{2}-\frac{5}{2}$$

Since \frac{56}{2} and \frac{27}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{56-27}{2}-\frac{5}{2}$$

Subtract 27 from 56 to get 29.

$$\frac{29}{2}-\frac{5}{2}$$

Since \frac{29}{2} and \frac{5}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{29-5}{2}$$

Subtract 5 from 29 to get 24.

$$\frac{24}{2}$$

Divide 24 by 2 to get 12.

$$12$$

Factor

$$2^{2}\times 3$$
