124+125+126+127+128+129+130=多少乘以多少?找出规律,改写成乘法算式.
124+130=127*2
125+129=127*2
126+128=127*2
所以:124+125+126+127+128+129+130
=(124+130)+(125+129)+(126+128)+127
=127*2+127*2+127*2+127
=127*7
=889
124+125+126+127+128+129+130=124+130+125+129+126+128+127=127*2+127*2+127*2+127=127*7
124+125+126+127+128+129+130=124+130+125+129+126+128+127
=127*2+127*2+127*2+127
=127*7
127*7=自己算
