Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♫`

Let's solve ~

Expression 1

`\qquad \sf  \dashrightarrow \: (1)/(2) (5 + 13) - 4.5`

`\qquad \sf  \dashrightarrow \: (1)/(2) (18) - 4.5`

`\qquad \sf  \dashrightarrow \: 9 - 4.5`

`\qquad \sf  \dashrightarrow \:4.5`

Expression 2

`\qquad \sf  \dashrightarrow \:(5 + 11) - (24 - 15) * 3`

`\qquad \sf  \dashrightarrow \:16 - (9 * 3)`

`\qquad \sf  \dashrightarrow \:16 - 27`

`\qquad \sf  \dashrightarrow \: - 11`

Expression 3

`\qquad \sf  \dashrightarrow \: {6}^(2) + (3 * 7) - (9 / 3)`

`\qquad \sf  \dashrightarrow \:36 + 21 - 3`

`\qquad \sf  \dashrightarrow \:57 - 3`

`\qquad \sf  \dashrightarrow \:54`
