这个题目的简单运算,就是找同类项,将0.34/3.4/34统一写成3.4再化简,
0.34x35+3.6x3.4+34x0.26
=0.34x10x35/10+3.4x3.6+34/10x0.26x10
=3.4x3.5+3.4x3.6+3.4x2.6
=3.4x(3.5+3.6+2.6)
=3.4x9.7
32.98

0.34×35+3.6×3.4+34×0.26
=0.34X35+36X0.34+0.34X26
=0.34x(35+36+26)
=0.34x97
=0.34x(100-3)
=0.34x100-0.34x3
=34-1.02
=32.98

0.34×35+3.4×3.6+34×0.26
=3.4×3.5+3.4×3.6+3.4×2.6
=3.4×(3.5+3.6+2.6)
=3.4×9.7
=3.4×(10-0.3)
=34-1.02
=32.98
