Question

98.76–4.5–0.26–5.5–1.74怎么简便计算？

Answer 1

=98.76-（4.5+0.26+5.5+1.74）

=98.76-12

=86.76

解法分析：把所有减项，提取-1，转化为加法。利用四则运算法则进行运算，同级运算按顺序计算，不同级运算先算高级运算，所以就可以很快得出结果。

Answer 2

98.76-4.5-0.26-5.5-1.74
=98.76-（4.5+5.5）-（0.26+1.74）
=98.76-10-2
=86.76

Answer 3

这道题用凑整法，1.74和0.26能凑成2，4.5和5.5能凑成10所以这道题的做法是 98.76－（4.5+5.5）－（0.26+1.74）= 98.76－10－2=88.76－2=86.76

Answer 4

98.76-(4.5+5.5)-(0.26+1.74)=86.76

Answer 5

98.76-4.5-0.26-5.5-1.74
=98.76-（4.5+5.5+0.26+1.74）
=98.76-（10+2）
=98.76-12
=86.76
