What number can you subtract half from to obtain a result that is zero?
The wording is ambiguous. If the questions means, "From what number can you subtract one-half to get a result of zero?" then the answer is one-half. (1/2) - (1/2) = 0 If the question means, "From what number can you subtract half of the number to get a result of zero?" then the answer is zero. 0 - (1/2)0 = 0
How do you get the percent of change?

If you subtract a number from itself or divide a number by itself which will give you the largest?
Subtracting a number by itself will leave you with 0, whereas dividing leaves 1. So dividing a number by itself will give the larger result.
What is the result if you pick a number from 1 to 9 and add this to the next higher number and add 9 and divide by 2 and subtract your starting number?
For the numbers 1 thru 9, the result is always 5. In fact, the result is 5 for any integer, and if you change the wording slightly to say 'add this to the original number plus 1' instead of 'add this to the next higher number' the result is 5 for ANY complex number. Here's why: Number picked: x Next higher number (for integers) or Number picked plus 1 (for any other sort of number): x + 1 Add them: x + x + 1 = 2x + 1 Add 9: 2x + 1 + 9 = 2x + 10 Divide by 2: x + 5 Subtract starting number: x + 5 - x = 5.

How is it possible to subtract a number from 100 and get a result that is greater than 100?
Subtract a negative, eg 100 - (-1) = 101.
How do you determine percentage of growth from one number to another?
You do the following: 1) Divide the second number by the first. This will give you a factor, for example 1.20. 2) Subtract 1 from the result. This gives you the increase as a factor, for example, 0.20. 3) Multiply the result by 100, to convert to a percentage. In this example, 20%.
How do you work out one percent of a number?
Divide the number by 100. The result is 1% of the number.
Formula of Celsius?
F to C Deduct 32, then multiply by 5, then divide by 9 C to F Multiply by 9, then divide by 5, then add 32 Answer 2: Here's a much easier way to do it: C to F: Double it, subtract 1/10 of the result, and add 32. F to C: Subtract 32, add 1/9 of the result, then divide by 2.
