8.3 - 4.9 =	60 ÷ 10000 =	510 - 60 =
288 +53 =	400 ÷ 25 =	125 ×56 =
19.5 × 100 =	8.6 + 52.5 =	50 - 8.56 =
2.33 × 1000 =	8.6 + 8.86 =	7.3 ÷ 1000 =
2、简便计算
768 × 1001 - 768	5.25 - (2.25 + 1.16 )	6000 ÷ 8 ÷ 125
8 × (88 × 125 )	298 + 444 + 202 + 807 + 156	( 125 + 70 ) × 8
3、四则运算与灵活运用
446 + 707 - 704	148 - 4160 ÷ (16 × 20)	125 × 88
87 × 850 ÷ 17	8.97 - 8.41 + 6.3	998 × 523
0.68 - 4.5 + 8.32	(81 × 9 + 115) × 4	[(83+67)÷5+184]×2
