Question

Simplify `[-4-28-:(-4-3)]-3(-4)`?

Answer 1

`[-4-28-:(-4-3)]-3(-4)=12`

Explanation:

Use order of operations (PEMDAS).
`[-4-28-:(-4-3)]-3(-4)`
`[-4-28-:(-7)]-3(-4)`
`[-4+4]-3(-4)`
`0-3(-4)`
`0+12`
`12`
Our answer is:
`12`

Answer 2

`12`

Explanation:

There are `2` terms in this expression. Determine an answer for each term.

Within each term, calculate the brackets first.
Then powers and roots (none in this case)
Then multiplication and division
Last addition and subtraction.

`color(blue)([-4-28div(-4-3)])color(red)(-3(-4))`
`color(white)(wwwwwwwwwww)darrcolor(white)(wwww)darr`
`=color(blue)([-4-28div(-7)])" "color(red)(+12)`
`color(white)(wwwwwwww)darr`
`=color(blue)([-4" "+4]" "color(red)(+12)`

`=color(blue)(0)" "color(red)(+12)`

`=12`
