You can also add, subtraction, multiply, and divide and complete any arithmetic you need. Step 2: Click the blue arrow to submit and see your result The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2 In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.. Standard deviation may be abbreviated SD, and is most commonly.

Example 1: Translate into mathematical expressions. (a) The sum of 6 and twice a number; Solution: The phrase twice a number translates into two times the number, or 2x.
