Solve {l}{+3*2*10+1.5*(20-6)}{+1.5*5+3+10}

$$\left. \begin{array} { l } { + 3 \times 2 \times 10 + 1.5 \times ( 20 - 6 ) } \\ { + 1.5 \times 5 + 3 + 10 } \end{array} \right.$$

Evaluate

$$101.5$$

Solution Steps

Multiply 3 and 2 to get 6.

$$6\times 10+1.5\left(20-6\right)+1.5\times 5+3+10$$

Multiply 6 and 10 to get 60.

$$60+1.5\left(20-6\right)+1.5\times 5+3+10$$

Subtract 6 from 20 to get 14.

$$60+1.5\times 14+1.5\times 5+3+10$$

Multiply 1.5 and 14 to get 21.

$$60+21+1.5\times 5+3+10$$

Add 60 and 21 to get 81.

$$81+1.5\times 5+3+10$$

Multiply 1.5 and 5 to get 7.5.

$$81+7.5+3+10$$

Add 81 and 7.5 to get 88.5.

$$88.5+3+10$$

Add 88.5 and 3 to get 91.5.

$$91.5+10$$

Add 91.5 and 10 to get 101.5.

$$101.5$$

Factor

$$\frac{7 \cdot 29}{2} = 101\frac{1}{2} = 101.5$$
