43.2 - 1.8×3 - 4.6
= 43.2 - 5.4 - 4.6
= 43.2 - (5.4 + 4.6)
= 43.2 - 10
= 33.2
= 43.2 - 5.4 - 4.6
= 43.2 - (5.4 + 4.6)
= 43.2 - 10
= 33.2

43.2-1.8*3-4.6
= 43.2 - (2-0.2)*3-4.6
= 43.2 - 6 + 0.6 - 4.6
= 43.2 - (6 + 4.6- 0.6)
= 43.2 - 10
= 33.2
= 43.2 - (2-0.2)*3-4.6
= 43.2 - 6 + 0.6 - 4.6
= 43.2 - (6 + 4.6- 0.6)
= 43.2 - 10
= 33.2
