15.37×7.88-9.37×7.38+1.537×21.2-93.7×0.262
是简便计算

原式=15.37x7.88+1.537x21.2 - 9.37x7.38-93.7x0.262
=15.37x7.88+15.37x2.12 - （9.37x7.38+9.37x2.62）
=15.37x（7.88+2.12）- 9.37x（7.38+2.62）
=15.37x10-9.37x10
=(15.37-9.37)x10
=6x10
=60
再问：能简略点么
再答：或
15.37*7.88-9.37*7.38+1.537*21.2-93.7*0.262
=1.537*（78.8+21.2）-9.37*（7.38+2.62）
=1.537*100-9.37*10
=153.7-93.7
=60
