N2 - By analyzing e+e- annihilation data with an integrated luminosity of 2.93 fb-1 collected at the center-of-mass energy s=3.773 GeV with the BESIII detector, we present the first absolute measurements of the branching fractions of twenty Cabibbo-suppressed hadronic D0(+) decays involving multiple pions. The highest four branching fractions obtained are B(D0→π+π-π0)=(1.343±0.013stat±0.016syst)%, B(D0→π+π-2π0)=(1.002±0.019stat±0.024syst)%, B(D+→2π+π-π0)=(1.165±0.021stat±0.021syst)%, and B(D+→2π+π-2π0)=(1.074±0.040stat±0.030syst)%.
