Question

- 1–8+9÷ - 1 answer this plz

Answer 1

Step-by-step explanation: -18

Answer 2

For this case we must resolve the following expression:

`-1-8 + \frac {9} {- 1}`

The division has priority over addition and subtraction, then
`\frac {9} {- 1} = - 9`:

`-1-8-9`

Knowing that equal signs are added and the same sign is placed:

`-1-8-9 = -18`

Answer:

`-1-8 + \frac {9} {- 1} = - 18`
