Question

直接寫(xiě)得數(shù)．

345+320=	448-140=	525+33=	996-81=
400×4=	200×7=	8×300=	0×576=
2 7 + 3 7 =	6 9 - 2 9 =	1- 1 4 =	3 6 + 3 6 =

Answer 1

分析：根據(jù)整數(shù)加減法、整數(shù)乘法和分?jǐn)?shù)加減法的計(jì)算方法進(jìn)行計(jì)算即可得到答案．

解答：解：

345+320=665	448-140=308	525+33=558	996-81=915
400×4=1600	200×7=1400	8×300=2400	0×576=0
2 7 + 3 7 = 5 7	6 9 - 2 9 = 4 9	1- 1 4 = 3 4	3 6 + 3 6 =1

點(diǎn)評(píng)：此題主要考查的是整數(shù)加減法、整數(shù)乘法和分?jǐn)?shù)加減法的計(jì)算方法的應(yīng)用．
