Sort

$$825,\ 925,\ 1050,\ 1125$$

Solution Steps

Multiply 40 and 20 to get 800. Multiply 5 and 5 to get 25.

$$sort(800+25,45\times 20+5\times 5,40\times 25+5\times 5+5\times 5,40\times 25+25\times 5)$$

Add 800 and 25 to get 825.

$$sort(825,45\times 20+5\times 5,40\times 25+5\times 5+5\times 5,40\times 25+25\times 5)$$

Multiply 45 and 20 to get 900. Multiply 5 and 5 to get 25.

$$sort(825,900+25,40\times 25+5\times 5+5\times 5,40\times 25+25\times 5)$$

Add 900 and 25 to get 925.

$$sort(825,925,40\times 25+5\times 5+5\times 5,40\times 25+25\times 5)$$

Multiply 40 and 25 to get 1000. Multiply 5 and 5 to get 25. Multiply 5 and 5 to get 25.

$$sort(825,925,1000+25+25,40\times 25+25\times 5)$$

Add 1000 and 25 to get 1025.

$$sort(825,925,1025+25,40\times 25+25\times 5)$$

Add 1025 and 25 to get 1050.

$$sort(825,925,1050,40\times 25+25\times 5)$$

Multiply 40 and 25 to get 1000. Multiply 25 and 5 to get 125.

$$sort(825,925,1050,1000+125)$$

Add 1000 and 125 to get 1125.

$$sort(825,925,1050,1125)$$

The list values are already in order.

$$825,925,1050,1125$$

Evaluate

$$825,\ 925,\ 1050,\ 1125$$
