9:3−1.5×2= 9:3-1.5\times2= 9:3−1.5×2=
According to the order of operations, we place the multiplication and division exercise within parentheses:
(9:3)−(1.5×2)= (9:3)-(1.5\times2)= (9:3)−(1.5×2)=
Now we solve the exercises within parentheses:
9:3=3 9:3=3 9:3=3
1.5×2=3 1.5\times2=3 1.5×2=3
And we obtain the exercise:
3−3=0 3-3=0 3−3=0
0
