6+8.4×1= 6+\text{8}.4\times1= 6+8.4×1=
According to rules of the order of operations , we must first place the multiplication exercise inside of parentheses:
6+(8.4×1)= 6+(8.4\times1)= 6+(8.4×1)=
Let's now proceed to solve the said expression:
8.4×1=8.4 8.4\times1=8.4 8.4×1=8.4
We should obtain the following exercise:
6+8.4=14.4 6+8.4=14.4 6+8.4=14.4
14.4
