36+75+64+125的簡便計(jì)算

簡便計(jì)算36+75加64+125

36+75+64+125 =(36+64)+(75+125) =100+200 =300

64+多少+36+125用簡便方法計(jì)算空分?jǐn)?shù)應(yīng)該填多少

64+多少+36+125用簡便方法計(jì)算空分?jǐn)?shù)應(yīng)該填多 64+多少+36+125 =(64+36)+(125+75) =100+200 =300

36+64×125用第等式計(jì)算,能簡便計(jì)算要簡便計(jì)算

36+64×125 = 36+8x125x8 = 8036

下面各題怎樣簡便就怎樣算.472+66+134 324+75+46+25+54 283+36+64+17 15+57+185 125+75+26+74

(1)472+66+134,
=472+(66+134),
=472+200,
=672;

(2)324+75+46+25+54,
=324+(75+25)+(54+46),
=324+100+100,
=524;

(3)283+36+64+17,
=(283+17)+(36+64),
=300+100,
=400;

(4)15+57+185,
=(15+185)+57,
=200+57,
=257;

(5)125+75+26+74,
=(125+75)+(26+74),
=200+100,
=300;

(6)98+(24+102),
=98+24+102,
=(98+102)+24,
=200+24,
=224.

138 +75 +62+ 125的簡便算法怎么算?

138 +75 +62+ 125 = 138 + 62 + 75 + 125 =200 + 200 =400 望采納
