18−1×0.1= 18-1\times0.1= 18−1×0.1=
According to the rules of the order of operations we should begin by placing the multiplication exercise within parentheses:
18−(1×0.1)= 18-(1\times0.1)= 18−(1×0.1)=
We then proceed solve the multiplication exercise:
1×0.1=0.1 1\times0.1=0.1 1×0.1=0.1
And we should obtain the following exercise:
18−0.1=17.9 18-0.1=17.9 18−0.1=17.9
17.9
