what is the net ionic equation for the reaction between a strong acid and a strong base?

what does it mean by this question?/ (: thanks.

Examples of acid/base reactions are
1. HCl + NaOH ==> H2O + NaCl
2. HNO3 + NaOH ==> H2O + NaNO3
3. HClO3 + NaOH ==> H2O + NaClO3
etc.
Note that an acid + base gives a salt + water. The salts are always spectator ions and the net ionic equation is
H^+(from the acid) + OH^-(from the base) ==> H2O
thank you Dr. Bob! I get it know.
