Question

3+5.8+11.49*5.8+11.49+17.34-3+5.8+11.49+17.34*5.8+11.49

Answer 1

3+5.8+11.49*5.8+11.49+17.34-3+5.8+11.49+17.34*5.8+11.49

=3+5.8-3+5.8+11.49*5.8+11.49+11.49+11.49 +17.34+17.34*5.8

=5.8+5.8+11.49*（5.8+1+1+1）+17.34+17.34*5.8

=11.49*8.8+5.8*（1+1+17.34）+17.34

=11.49*8.8+5.8*19.34+17.34

我只能做到这里啦,下面就没法简算啦.

可能其他知友有更好的方法.
