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
