2.36+0.88-2.63+0.21的解便方法？

Answer 1

2.36+0.88-2.63+0.21的解便方法？
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：

2.36+0.88-2.63+0.21

=3.24-2.63+0.21

=0.61+0.21

=0.82

存疑请追问，满意请采纳

Answer 2

2.36+0.88－2.63+0.21
＝3.24－（2.63－0.21）
＝3.24－2.42
＝3.24－2.24－0.18
＝1－0.18
＝0.82

Answer 3

原式=2.36+0.88+0.21-2.63
=2.36+1.09-2.63
=3.45-2.63
=3.45-2-0.63
=1.45-0.63
=0.82
