One way:-- Subtract the discount percent number from 100 .-- Multiply the result by the dollar amount.-- Divide the result by 100 .-- The result is the discounted amount.===============================Another way:-- Multiply the dollar amount by the discount percent number.-- Divide the result by 100 .-- Subtract the result from the original dollar amount.-- The result is the discounted amount.
You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.
n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
-- Take the number of sides in the polygon. -- Subtract 2. -- Multiply the result by 180 degrees. -- You got it.

Multiply the number by the percent in decimal form, and subtract the result from the original number. Alternatively, multiply the number by (1 - the percent).

You have an original value and a new value. Take the new value and subtract the original value. Then divide that number by the original value.
Take the last digit of a number and subtract eleven times from the rest of that number. If the result is 0 or divisible by 37, then so was the original number.

You do one of two things. Take the original price, multiply it by .15, and then subtract the result from the original. Or you can multiply the original by .85 (1.00-.15) and get the reduced price immediately.
take the largest number in the sample and subtract the smallest number that is the range
-- Take the number of sides in the polygon. -- Subtract 2. -- Multiply the result by 180 degrees. -- You got it.
Osmium, if you take the Atomic Mass (190.2) and subtract the Atomic number (76), you get the result of 114, this is the number of protons, not the protons and neutrons combined.
