What are they?
Formulas and calculations are mathematical expressions used to determine a specific value based on other values. They are like instructions written in a language that computer systems can understand and execute.
Sum:
The sum of two or more numbers is the total of their values.
Example:
Sum of 5 and 10 = 15
Avg:
The average, or average, of a set of numbers is the sum of the numbers divided by the number of values.
Example:
Average of 5, 10, and 15 = 12.5
Other formulas:
Difference: Difference = Original value - New value
Multiplication: Multiplication = Original value x New value
Division: Division = Original value ÷ New value
How to use them:
Identify the variables (the unknown values) in the formula.
Substitute the corresponding values into the formula.
Perform the mathematical operation indicated by the formula.
The result is the answer.
Examples:
2 + 7 = 9 (Sum of 2 and 7)
10 ÷ 2 = 5 (Division of 10 by 2)
3 x 4 = 12 (Multiplication of 3 and 4)
15 - 5 = 10 (Difference between 15 and 5)
