it would be 91 because if you add 36+55 it would equal 91 :)
91 is the dialling code for India. So you would add plus 91 (normally not plus plus 91) to dial a mobile with an Indian number. The phone need not be in India.
It's not possible to write down all the multiples of 91. If you brought me a number and told me that your number is the largest multiple of 91, then no matter how large your number was, all I would have to do would be to add 91 to it, and I would have another multiple of 91 that's larger than your number. There are an infinite number of them.

First add all the addition together and add all the subtraction together. Then there will be the total addition and the total subtraction. Subtract the total subtraction from the total addition.99+98-97+96-95+94-93+92-91+90=(99+98+96+94+92+90)-(97+95+93+91)=569-376=193

Add the series of data together to get a total - then divide that by the number of pieces of data. For example - say you wanted to find the average for the numbers 12, 8, 32, 19 & 20. Add them together, and you get 91. Then 91 divided by 5 (there are five numbers) is 18.2

Well, if .91 is equal to 1-X then you could add X to both sides to get .91 + X = 1, then subtract .91 from both sides. You would be left with X = .09. If X was what you were trying to solve for for.
