Always do what's in the parens first. So it's 1 1/10 divided by 90.
(11-10 is supposed to be 1 1/10th, right?)

1. Solve what's in the parentheses (10x9= 90).
2. Solve what's on the top of the line (11-10= 1).
3. Divide (1/90).
A good way to remember the order of operations is:
Parentheses (Please)
Exponents (Excuse)
Multiplication (My)
Division (Dear)
Addition (Aunt)
Subtraction (Sally)

11-10/10x9.
This really depends on how the problem was expressed. If it was given to you in the form (11-10)/(10x9) your answer would be 1/90.
If it was express as 11-10/10 x 90..Do the divison first to yield 11 - 1 x 90..11-90..To give an answer of -79.
Hope this helps you

first do 10x9 which equals 90 the do 10-11 which equals 1 then the problem is 1 divided by 90 which equals .01 repeating

11-10 divided by (10x9)=
11-10 divided by 90
10 divided by 90 is .1111111......
so just use .11
11-.11= 10.89
10.89

I don't know the answer (but I do now after reading all the answers from the smart people out there)!
I must say, it suddenly made me feel real stupid. At the age of 58 and one who is a college graduate, it amazes me how soon we forget all those little secrets we once knew.
Don't feel bad about having to ask.
I think I'll go back to my room and cry.

the order is really simple just remember:
Please
Excuse
My
Dear
Aunt
Sally
the first letter of each word stands for something:
P- paranthesis
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
multiplication and division are done first from left to right
same goes for addition and subtraction
so the answer to your question would be:
1 divided by 90 = 1/90
