Question

Place these signs (+ -) between the numerals to make the number equation correct: 5 07 2 0 7 4 = 304

Answer 1

The posible numbers are:

$5\text{ }0\text{ 7 2 0 7 4=304}$

So if we put the sign we can have:

$507-207+4=304$

and we can solve the equation to confirm it so:

$\begin{gathered} 300+4=304 \\ 304=304 \end{gathered}$
