4.52*4.4+4.52*5.5+0.452【用简便计算】

4.52*4.4+4.52*5.5+0.452【用简便计算】
4.52*4.4+4.52*5.5+0.452
=4.52*(5.5+4.4+0.1)
=4.52*10
=45.2

4.52*4.4+4.52*5.5+0.452
=4.52*(5.5+4.4+0.1)
=4.52*10
=45.2

4.52×4.4+4.52×5.5+0.452
=4.52×(5.5+4.4+0.1)
=4.52×10
=45.2

4.52×4.4+4.52×5.5+0.452
=4.52×(5.5+4.4+0.1)
=4.52×10
=45.2

4.52*4.4+4.52*5.5+4.52*0.1
=4.52*(4.4+5.5+0.1)
=4.52*10
=45.2

4.52*4.4+4.52*5.5+0.452
= 4.52*4.4+4.52*5.5+0.1
= 4.52*(4.4+5.5+0.1)
= 4.52*10
= 45.2
