a node, the sum of the currents is 0. Please keep in mind that currents have directions. Currents incoming have negative values, while currents outgoing have positive values.
$\sum\limits_{i=1}^n(I_i) = 0$

The sum of the voltage in a circuit loop is equal to the power source voltage.
$E = \sum\limits_{i=1}^n(U_i)$
