Yes, IF the variable has been declared, has a value, and is of a numerical type such that your addition operator can perform the operation on the number and the value of that type variable. The compiler or interpreter will look up the variable's value, substitute it for the variable, and perform the addition just as if your statement used two numbers. First example: If your number is an integer and your variable is of type real, almost any addition operator can successfully add the two. Second example: If your number is a real and your variable is a character type (with a value, say, of "Smith"), the addition will obviously fail. In many languages, however, variables of type Boolean may be handled arithmetically, as the value True equals 1 and False is zero.

How do you find the average of rows and columns in a 2d array in java?

You can add them.
Can you add or subtract a number with a variable and a number without one?
Yes, you can add or subtract a number with a variable and a number without one, but they cannot be combined into a single term. For example, you can simplify the expression (3x + 5) to show that it consists of a variable term (3x) and a constant term (5), but they remain separate. The result is (3x + 5), not a single term.
How do you transform a negatively-skewed variable?
Add 1 to the largest value and then add that number to all results to obtain the new distribution
What is the answer to -5 plus a equals 21?
