    A circuit has 120 volts and 5 amps. Calculate the vars.

    Seems straight forward but it looks more like a watt/power calculation to me instead of a vars, am I missing something?

    Volt-amperes-reactive=vars

    What are the vars. I'm not familiar with that terminology.

    I believe the term VARs stands for Volt-Amps Reactive.

    I would have expected a phase angle to be included in the problem.

    With no more than the information given, the only answer is plain old unreactive power - 600 watts. Don't you need some additional information for figuring reactive power?
