Solve {l}{7*9}{5*4}{7*7}{10^9*5}

$$\left. \begin{array} { l } { 7 \times 9 } \\ { 5 \times 4 } \\ { 7 \times 7 } \\ { 10 ^ { 9 } \times 5 } \end{array} \right.$$

Sort

$$20,49,63,5000000000$$

Solution Steps

Multiply 7 and 9 to get 63.

$$sort(63,5\times 4,7\times 7,10^{9}\times 5)$$

Multiply 5 and 4 to get 20.

$$sort(63,20,7\times 7,10^{9}\times 5)$$

Multiply 7 and 7 to get 49.

$$sort(63,20,49,10^{9}\times 5)$$

Calculate 10 to the power of 9 and get 1000000000.

$$sort(63,20,49,1000000000\times 5)$$

Multiply 1000000000 and 5 to get 5000000000.

$$sort(63,20,49,5000000000)$$

To sort the list, start from a single element 63.

$$63$$

Insert 20 to the appropriate location in the new list.

$$20,63$$

Insert 49 to the appropriate location in the new list.

$$20,49,63$$

Insert 5000000000 to the appropriate location in the new list.

$$20,49,63,5000000000$$

Evaluate

$$63,\ 20,\ 49,\ 5000000000$$
