102x85

102×85 =100×85+2×85 =8500+170 =8670

102*85 = 8670 验算:8670÷102=85 或者:8670÷85=102

102x85简便计算 =(100+2)*85 =100*85+2*85 =8500+170 =8670

102X85 =100×85+2×85 =8500+170 =8670 99Xl76 =100×176-176 =17600-176 =17424 16XI25X25 =8×125×2×25 =1000×50 =50000 5600÷16÷5 =5600÷(16×5) =5600÷80 =70

我看到这个问题太晚了

请采纳

14.8÷0.125+85.2×8 =14.8÷1/8+85.2×8 =14.8×8+85.2×8 =(14.8+85.2)×8 =100×8 =800
