Question

2.2✖️3.3➕3.3✖️4.4➕4.4✖️5.5的简便算法怎么算

Answer 1

2.2×3.3+3.3×4.4+4.4×5.5
=2.2×3.3+2.2×2（3.3+5.5）
=2.2×（3.3+17.6）
=2.2×20.9
=45.98

Answer 2

2.2✖️3.3➕3.3✖️4.4➕4.4✖️5.5
=（2x3）（1.1x1.1）+（3x4）（1.1x1.1）+（4x5）（1.1x1.1）
=（6+12+20）x1.21
=38x1.21
=45.98

Answer 4

2.2✖️3.3➕3.3✖️4.4➕4.4✖️5.5的简便算法
2.2✖️3.3➕3.3✖️4.4➕4.4✖️5.5
=2.2*3.3+3.3*2*2.2+2.2*2*5.5
=2.2*3.3+2.2*6.6+2.2*11
=2.2*(3.3+6.6)+2*1.1*11
=2.2*(10-0.1)+2*12.1
=22-0.22+24.2
=45.98
