Adding two (or more) numbers means to find their sum (or total). Subtracting one number from another number is to find the difference between them. Multiplication means times (or repeated addition). A product is the result of the multiplication of two (or more) numbers.

Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us by how much a number differs from the other.

Finding the difference between two numbers is a form of subtraction. In these Maths problems, the aim is to find how many numbers lie between two given numbers. This is a similar process to finding the range between two numbers.

SUM – The sum is the result of adding two or more numbers. DIFFERENCE – The difference of two numbers is the result of subtracting these two numbers. PRODUCT – The product of two or more numbers is the result of multiplying these numbers.

Subtraction (which is signified by the minus sign −) is one of the four arithmetic operation along with addition, multiplication and division. Subtraction is an operation that represents removal of objects from a collection.

: the quality or state of being dissimilar or different. the difference between right and wrong. : an instance of being unlike or distinct in nature, form, or quality.

The SUM function will return the sum of all NON missing values across variables while addition will return a missing value if there any missing values in the variables.

Here are a few possibilities based on common English usage rather than pure mathematical considerations... "The difference between ( 8 times a number ) and 9 is 4 ." This is a good "mathematical" interpretation. "The difference between ( 8 times a number ) and ( 9 times the same number ) is 4 ."

The mean difference (more correctly, 'difference in means') is a standard statistic that measures the absolute difference between the mean value in two groups in a clinical trial. It estimates the amount by which the experimental intervention changes the outcome on average compared with the control.

Square number “6 is not a perfect square” ; “9 is a perfect square”. Factor “6 is divisible by 4 numbers (1,2,3,6)” ; “9 is divisible by 3 numbers (1,3,9)”. Even or Odd “6 is even number” ; “9 is odd number”.
