Answer:
(22÷2)-0! = 10
2+2+2+0! = 7
Step-by-step explanation:
(22÷2)-0!=
Divide 22÷2 first bc its inside the parenthesis, get:
11 - 0! Next evaluate the factorial (yes, exclamation mark is a mathematical operation and 0! equals 1)
11 - 1 subtract
10
Next, 2+2+2+0! =
2+2+2+1=

1.0649 to the nearest thousandths is 1.065
You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right.
If it's 5 or higher, round up.
If it's 4 or lower, round down.
Since it is 9, we round up.
The 4 turns into a 5.
So, 1.065
