Question

How do you solve 4 times 7 plus a number is 28?

Answer 1

The number is `0`

Explanation:

If we let the number be represented by `n`
there are two interpretations of this question:
`color(white)("XXX")4 xx (7+n)=28`
and
`color(white)("XXX")(4xx7) +n=28`

Fortunately (or coincidentally) both simplify to `n=0`
