Solve 9*2+15:3+4+12:4*2-3*5*2=

$$9 \times 2 + 15 : 3 + 4 + 12 : 4 \times 2 - 3 \times 5 \times 2 =$$

Evaluate

$$3$$

Solution Steps

Multiply 9 and 2 to get 18.

$$18+\frac{15}{3}+4+\frac{12}{4}\times 2-3\times 5\times 2$$

Divide 15 by 3 to get 5.

$$18+5+4+\frac{12}{4}\times 2-3\times 5\times 2$$

Add 18 and 5 to get 23.

$$23+4+\frac{12}{4}\times 2-3\times 5\times 2$$

Add 23 and 4 to get 27.

$$27+\frac{12}{4}\times 2-3\times 5\times 2$$

Divide 12 by 4 to get 3.

$$27+3\times 2-3\times 5\times 2$$

Multiply 3 and 2 to get 6.

$$27+6-3\times 5\times 2$$

Add 27 and 6 to get 33.

$$33-3\times 5\times 2$$

Multiply 3 and 5 to get 15.

$$33-15\times 2$$

Multiply 15 and 2 to get 30.

$$33-30$$

Subtract 30 from 33 to get 3.

$$3$$

Factor

$$3$$
