to ensure and re-check your work you use the opposite signs (addition & subtractions, multiplication & division)
e.g.
__= blank
10+ _ = 12
_=2
to check: you take the answer (in this case 12) and subtract (because its the opposite of addition) by the blank you filled in (2 in this case.
therefore, 12-2=10 so we know its correct :-)
