[SOLVED] Derived Variable from variable itself

Is it possible to create derived variable from itself? I would like to update variable value by decreasing value with the amount of other variable. Something like this {VARIABLE_A} = {VARIABLE_A}-{VARIABLE_B}

Greetings dear user, as Ubidots variables are basically time series, you cannot overwrite its values in a massive math operation. For your specific example, you should create a third variable C to store the result of {var_A} - {var_b}.

All the best
