如题所述
递等式计算64-2.5×4.1
解题思路:四则运算规则(按顺序计算,先算乘除后算加减,有括号先算括号,有乘方先算乘方)即脱式运算(递等式计算)需在该原则前提下进行
解题过程:
64-2.5×4.1
=64-10.25
=53.75

64-2.5×4.1
=64-(2.5×4+2.5×0.1)
=64-(10+0.25)
=64-10-0.25
=54-0.25
=53.75
=64-(2.5×4+2.5×0.1)
=64-(10+0.25)
=64-10-0.25
=54-0.25
=53.75

64-2.5x4.1
=64-2.5x(4+0.1)
=64-2.5x4-2.5x0.1
=64-10-0.25
=54-0.25
=53.75
最后结果等于53.75。
=64-2.5x(4+0.1)
=64-2.5x4-2.5x0.1
=64-10-0.25
=54-0.25
=53.75
最后结果等于53.75。
