30 divided by 12 plus 10 = 12 1/2 (12.5)
Take the number in centigrade and multiply it by 9. Take that number and divide by 5. Take that number and add 32.
You take the original value times 0.25. That number is 25% of the original, so you take the original number minus that number.
subtraction means you have to take away from the number
no
take the largest number in the sample and subtract the smallest number that is the range
yes if u take a negative from a positve you will get a negative
NO!!!! sqrt(-n) ????? However, -n X -n = (+)n^2 Sqrt(n^2) = either -n or (+)n , because either -n X -n = (+)n^2 or n x n = n^2 However, sqrt(-n) takes us into IMAGINARY numbers. sqrt(-n) = sqrt( -1 x n) = sqrt(-1) X sqrt(n) .The sqrt(-1) is mathemtically unresolved and is given the symbol 'i' (small / lower case letter 'i'. The sqrt(n) .being positive can be found.
It are take many to get ni number, no really - more than a lot.
It is subtraction
Multiply the number by 0.1
Multiply the number by 0.15
Yes, then you get a negative number left over
