Question

请问32.81×99+32.81×10的简便运算是怎么做的呢？

Answer 1

32.81×99+32.81×10
=32.81×100+32.81×10-32.81
=3281+328.1-32.81
=3609.1-32.81
=3576.29
所以，可以通过上面的简便计算过程运算进行详细计算，得到答案是3576.29。

Answer 2

32.81×99+32.81×10

=32.81×（100-1）+328.1

=3281-32.81+328.1

=3576.29

Answer 3

你好，这道题可以这样做：32.81×99+32.81×10=32.81×（99+1）+32.81×10－32.81=32.81×100+32.81×10－32.81=3281+328.1－32.81=3576.29

Answer 4

32.81×（100-1）+32.81×10
=3281-32.81+328.1
=3248.19+328.1
=3576.29

Answer 5

答：简便运算如下：
32.81x99＋32.81x10
＝32.81x（100－1）＋328.1
＝32.81x100－32.81x1＋328.1
＝3281－32.81＋328.1
＝3248.19＋328.1
＝3576.29
