14.37×7.88-9.37×7.38+1.437×21-93.7×0.262
=14.37x7.88-9.37x7.38+14.37x2.1-9.37x2.62
=14.37x(7.88+2.1)-9.37x(7.38+2.62)
=14.37x(10-0.02)-9.37x10
=14.37x10-14.37x0.02-9.37x10
=143.7-0.2874-93.7
=143.7-93.7-0.2874
=50-0.2874
=49.7126
=14.37x7.88-9.37x7.38+14.37x2.1-9.37x2.62
=14.37x(7.88+2.1)-9.37x(7.38+2.62)
=14.37x(10-0.02)-9.37x10
=14.37x10-14.37x0.02-9.37x10
=143.7-0.2874-93.7
=143.7-93.7-0.2874
