8 + x
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
2n/5 or (2/5)*n
Variable means subject to change, able to vary or differ. Example : "In summer, the mountain weather was always variable." In algebra, a variable is a symbol, usually a letter, that represents one or more unknown or changing number. Example : "The variable is found using the proper equation."
The are used to represent numbers using powers of ten.
13 = D in hex. If you're using two digits to represent the hex number - its 0D
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
Circle graphs are use to illustrate the breakdown of a single variable into its components.
The total number of rows in a truth table can be calculated using the formula 2^n, where n is the number of variables. Each variable can have two possible truth values (True or False), so each row represents a unique combination of truth values for the variables.
In Algebra a term is either a single number or variable, or numbers and variables multiplied together.
2n/5 or (2/5)*n
A single statement, using variables, can convey the same information as many, sometimes infinitely many, statements.
To swap two numbers N1 and N2, using a third variable T... T = N1; N1 = N2; N2 = T;
Depending on the language you are using the default of an instance variable can be '0', 0, null, empty, '', or have a random number.
The standard variable is a representation of a number. Variables are typically letters that can be distinguished from numbers. The most common examples of a variable is x, y, or z. Variables that you should stay away from using are t (because it looks like an addition sign), and o (because it looks like a zero).Ex: 5x+5=15* * * * *Variables can be used to represent simultaneously mathematical procedures for a number of different values.So, for example, 5x+5 stands for "multiply your variable by 5 and add 5". For each value of the variable x, this will give a different result, but the advantage of using this notation is that you can process all of them together instead of individually.
You put that number with a little number over it depending on how many times that number is multiplied by itself.
When a firm attains minimum average variable cost, the number of units of labor it is using depends on the average product.
