答案和解析
(1)13.8+9.6-12.5
=23.4-12.5
=10.9
(2)13.26-5.12-4.88
=13.26-(5.12+4.88)
=13.26-10
=3.26
(3)5.18+5.67+3.82+4.33
=(5.18+3.82)+(5.67+4.33)
=9+10
=19
(4)6.5-2.6+0.4
=3.9+0.4
=4.3
(5)35.7+(5.94-0.98)
=35.7+4.96
=40.66
(6)6.32+5.46-3.32+4.54
=(6.32-3.32)+(5.46+4.54)
=3+10
=13
=23.4-12.5
=10.9
(2)13.26-5.12-4.88
=13.26-(5.12+4.88)
=13.26-10
=3.26
(3)5.18+5.67+3.82+4.33
=(5.18+3.82)+(5.67+4.33)
=9+10
=19
(4)6.5-2.6+0.4
=3.9+0.4
=4.3
(5)35.7+(5.94-0.98)
=35.7+4.96
=40.66
(6)6.32+5.46-3.32+4.54
=(6.32-3.32)+(5.46+4.54)
=3+10
=13
