Solve 1/10(-1*1+0*2+1*3+3*3+6*1)=

$$\frac { 1 } { 10 } ( - 1 \cdot 1 + 0 \cdot 2 + 1 \cdot 3 + 3 \cdot 3 + 6 \cdot 1 ) =$$

Evaluate

$$\frac{17}{10}=1.7$$

Solution Steps

Multiply -1 and 1 to get -1. Multiply 0 and 2 to get 0. Multiply 1 and 3 to get 3. Multiply 3 and 3 to get 9. Multiply 6 and 1 to get 6.

$$\frac{1}{10}\left(-1+0+3+9+6\right)$$

Add -1 and 0 to get -1.

$$\frac{1}{10}\left(-1+3+9+6\right)$$

Add -1 and 3 to get 2.

$$\frac{1}{10}\left(2+9+6\right)$$

Add 2 and 9 to get 11.

$$\frac{1}{10}\left(11+6\right)$$

Add 11 and 6 to get 17.

$$\frac{1}{10}\times 17$$

Multiply \frac{1}{10} and 17 to get \frac{17}{10}.

$$\frac{17}{10}$$

Factor

$$\frac{17}{2 \cdot 5} = 1\frac{7}{10} = 1.7$$
