简便计算:8.02-3.95+0.98-1.05原式=(8.02+0.98)-(3.95+1.05)=9-5=4简便计算:8.02-3.95+0.98-1.05原式=(8.02+0.98)-(3.95

简便计算:8.02-3.95+0.98-1.05原式=(8.02+0.98)-(3.95+1.05)=9-5=4
简便计算:8.02-3.95+0.98-1.05
原式=(8.02+0.98)-(3.95+1.05)=9-5=4

简便计算:8.02-3.95+0.98-1.05原式=(8.02+0.98)-(3.95+1.05)=9-5=4
8.02-3.95+0.98-1.05
=(8.02+0.98)-(3.95+1.05)
=9-5
=4

(8.02+0.98)-(3.95+1.05)=4

8.02-3.95+0.98-1.05
=8.02+0.98-(3.95+1.05)
=9-5
=4

=(8.02+0.98)-(3.95+1.05)
=9-5
=4

就是
8.02-3.95+0.98-1.05
=(8.02+0.98)-(3.95+1.05)=
9-5
=4
望采纳

8.02-3.95+0.98-1.05
=8.02+0.98-(3.95+1.05)
=9-5
=4
