126x33 74x33简便计算

126x35+74x33=126x(33+2)+74x33=126x33+126x2+74x33=(126+74)x33+126x2=200x33+252=6600+252=6852

你好!(246-126)x33=100x33=3300 仅代表个人观点,不喜勿喷,谢谢.

126*33+74*33=33*(126+74)=33*200=6600

299x33+33=33*(299+1)=33*300=9900

利用乘法分配律简便计算101*33-33=(101-1)*33=100*33=3300

299x33十33=(299+1)x33=300*33=9900

126*33+74*33= (126+74)*33= 200*33= 6600

原式=126x33=126x30+126x3=3780+378=4158

199X33十33=(199+1)x33=200x33=6600

125x25x33=125X[25X(32+1)] =125X[25X4X8+25] =125X[800+25] =125X800+[(00+25)X25] =100000+2500+625 =103125
