Indeed, for some gems, such as diamonds, the price per carat can increase exponentially as the gem size increases. Therefore, a 1 carat stone may cost $1,000 while a 2 carat stone may cost $4,000. This means that good quality sapphires and rubies in larger sizes tend to have a much higher price per carat.
Re: Convert positive # to negative. Hi, if you positive number is in A1, use the following formula to convert it to a negative number =A1*-1 Time values can not be negative. Microsoft MVP http://www.teylyn.com Twitter: http://twitter.com/IngeborgNZ. Microsoft MVP.
No, it will be a positive. Subtracting a negative number is the same as adding its negative value, which is a positive number. 4 - (-3) = 4 + 3 = 7 Other examples For 5-(-7), â¦ when there is a negative of a negative, you cross out the negatives and put a plus in their place.See 5+7 and then you solve the problem, 12. negative minus a negative turns the latter into a plus positive, for example -6 minus -3 would be : -6 ++ 3 = -3. A minus negative always turns into a plus positive... To get more Specific: Suppose x and y are two POSITIVE numbers so that-x and-y are negative.
