Question

How do you simplify `2(3-4) + 6` using PEMDAS?

Answer 1

`4`

Explanation:

There are two terms. Simplify each one separately and then add the answers together at the end.

Simplify the parentheses first, then multiply,

`" "color(blue)(2(3-4)) " "color(green)(+" "6)`
`color(white)(xxxx)darr`
`=color(blue)(2(-1)) " "color(green)(+" "6)`
`color(white)(xxx)darr`
`=color(blue)(-2) " "color(green)(+" "6)`

`=4`

Answer 2

`4` - One must put in his/her mind that PEMDAS is not optional.

Explanation:

`2(3-4)+6`

`=2*(-1)+6`

`=-2+6`

`=4`
