Simple calculation: 3.2 + 3.2 * 7 5 / 9 + 1 4 / 9 times 3 1 / 5


3.2 + 3.2 * 7 5 / 9 + 1 4 / 9 times 3 1 / 5
=3.2 * 1 + 3.2 * 7 and 5 / 9 + 1 and 4 / 9 * 3.2
=3.2 * (1 + 7 5 / 9 + 1 4 / 9)
=3.2*10
=32



3.288 times - 9 + (- 3.272) times 9 - (- 1.5) times 9


3.288 times - 9 + (- 3.272) times 9 - (- 1.5) times 9
=(-3.228-3.272+1.5)x9
=(-6.5+1.5)x9
=-5x9
