Solve {c}{12-4*3/10+2}{5*1.4-12:1.2}

$$\left. \begin{array} { c } { \frac { 12 - 4 \times 3 } { 10 + 2 } } \\ { 5 \times 1.4 - 12 : 1.2 } \end{array} \right.$$

Sort

$$-3,0$$

Solution Steps

Multiply 4 and 3 to get 12.

$$sort(\frac{12-12}{10+2},5\times 1.4-\frac{12}{1.2})$$

Subtract 12 from 12 to get 0.

$$sort(\frac{0}{10+2},5\times 1.4-\frac{12}{1.2})$$

Add 10 and 2 to get 12.

$$sort(\frac{0}{12},5\times 1.4-\frac{12}{1.2})$$

Zero divided by any non-zero number gives zero.

$$sort(0,5\times 1.4-\frac{12}{1.2})$$

Multiply 5 and 1.4 to get 7.

$$sort(0,7-\frac{12}{1.2})$$

Expand \frac{12}{1.2} by multiplying both numerator and the denominator by 10.

$$sort(0,7-\frac{120}{12})$$

Divide 120 by 12 to get 10.

$$sort(0,7-10)$$

Subtract 10 from 7 to get -3.

$$sort(0,-3)$$

To sort the list, start from a single element 0.

$$0$$

Insert -3 to the appropriate location in the new list.

$$-3,0$$

Evaluate

$$0,\ -3$$
