52

-52

20

-20

Answer 1

For this case we must resolve the following expression:

`(-6) ^ 2- \frac {28} {4} + (- 9) =`

Simplifying keeping in mind that:

`- * - = +\\+ * - = -`

`36- \frac {28} {4} -9 =`

Simplifying keeping in mind that:
`\frac {28} {4} = 7`

`36-7-9 =`

Simplifying keeping in mind that:

Equal signs are added and the same sign is placed:

`36-16 =`

Simplifying keeping in mind that:

Different signs are subtracted and the sign of the major is placed:

`36-16 = 20`
