Reaction enthalpy

In order to calculate a reaction enthalpy from enthalpis of formation, one simply adds up the enthalpies of the products time their stoichiometric coefficients, and substracts a similar sum for the reactants:

ΔHrxn = Σ(nprod * ΔHf, prod) - Σ(nreact * ΔHf, react)

Enthalpies of Formation (kJ/mol)
A -246
B 216
C -267
D -174

Based on the above data, calculate the enthalpy of the following reaction and indicate if the reaction is endothermic or exothermic:
2 A + B → 3 C + 2 D
Reaction Enthalpy:
