Answer 2

Answer:

Missing number = 68

Step-by-step explanation:

You can simply set up an equation like so: $x+(-56)=12$.

Then, proceed to solve by isolating the x by itself.

x+(-56)=12

   +56   +56  <--- Do the opposite operation on both sides to cancel the 56.

x=68

A quick pointer: A number plus a negative number is just subtracting so you can just work backwards.

Answer: 68.
