Solution Steps

Multiply 3 and 4 to get 12. Multiply 5 and 4 to get 20. Multiply 4 and 1 to get 4.

$$12\times 2+20+1.5\times 1+1.5\times 1+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 12 and 2 to get 24.

$$24+20+1.5\times 1+1.5\times 1+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Add 24 and 20 to get 44.

$$44+1.5\times 1+1.5\times 1+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 1.5 and 1 to get 1.5.

$$44+1.5+1.5\times 1+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Add 44 and 1.5 to get 45.5.

$$45.5+1.5\times 1+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 1.5 and 1 to get 1.5.

$$45.5+1.5+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Add 45.5 and 1.5 to get 47.

$$47+5\times 1.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 5 and 1.5 to get 7.5.

$$47+7.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Add 47 and 7.5 to get 54.5.

$$54.5+1.5\times 4\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 1.5 and 4 to get 6.

$$54.5+6\times 2+\left(5-1-1\right)\times 4+4\times 2$$

Multiply 6 and 2 to get 12.

$$54.5+12+\left(5-1-1\right)\times 4+4\times 2$$

Add 54.5 and 12 to get 66.5.

$$66.5+\left(5-1-1\right)\times 4+4\times 2$$

Subtract 1 from 5 to get 4.

$$66.5+\left(4-1\right)\times 4+4\times 2$$

Subtract 1 from 4 to get 3.

$$66.5+3\times 4+4\times 2$$

Multiply 3 and 4 to get 12.

$$66.5+12+4\times 2$$

Add 66.5 and 12 to get 78.5.

$$78.5+4\times 2$$

Multiply 4 and 2 to get 8.

$$78.5+8$$

Add 78.5 and 8 to get 86.5.

$$86.5$$

Factor

$$\frac{173}{2} = 86\frac{1}{2} = 86.5$$
