Explain how the subtraction of integers is related to the addition of integers?
Subtraction of integers is essentially addition of integers except the second integer is inverted. For example: 5 + 3 = 8 is a simple addition of integers. 5 - 3 = 5 is a simple subtraction of integers. It can be expressed by inverting the second value (the one right after the subration sign) and then switching the subtraction sign to an addition sign. So it would look like: 5 + (-3) = 5. Note that (-3) is the opposite of 3. So to do a more confusing subtraction problem like: 55 - (-5), we could rewrite this as: 55 + -(-5). From here it's easy to see that the two negatives cancel out. 55 + 5 = 60.
Explain when an binary operation is commutative?
when we add and substract any number * * * * * "substract" is not a word, and in any case, subtraction is not commutative. A binary operation ~, acting on a set, S, is commutative if for any two elements x, and y belonging to S, x ~ y = y ~ x Common binary commutative operations are addition and multiplication (of numbers) but not subtraction nor division.
What is the explanatory variable?
An explanatory variable is one which may be used to explain or predict changes in the values of another variable. There may be several explanatory variables.
A researcher tries to explain or bring about resulting changes in the response variable by performing an experiment which introduces an explanatory variable?
Answer is True... Via ApexVs
Explain what borrow trade regroup mean in subtraction?
it means to take away and borrow means to take away and regroup means to rearrang(make problem
How can you explain subtraction?
You can either explain it as "taking away" something, or as the inverse of addition, as in "how much do I need to add, to get such-and-such a result".
Explain why mixing color of light is called color addition but mixing pigmean is called color subtraction?
Because it is.
Explain how to write and evaluate an algebraic expression.thirteen less than the quotient of forty and a number; evaluate when n = 2?
Sample Response: Replace keywords with variables, numbers, and operations. Less than is subtraction, and the quotient is division. Order matters with subtraction and division. The expression is 40 n -13. To evaluate is the expression, substitute 2 in for the variable, and then use order of operations to simplify. The value when n = 2 is 7.
Explain how to write and evaluate an algebraic expression.one more than the product of a number and seven, decreased by five; evaluate when n = 6?
Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
Explain why does addition works?
Addition works because like all mathmatics as long as you know 1/2 of the equation, answer, and type of equation (addition,subtraction,multiplication, or division) there is only 1 answer.
Explain why you cannot find a numerical value for the expression 4x - 5y for x equals 3?
You cannot because the expression still contains the unknown variable y.

What do order of operations means explain?
Order of Operations is like when you have a problem i always use PEMDAS it means parenthesis, expoents, mulitipication, divide, addition, Subtraction follow it.
How do you explain the law of variable proportion?
Explain the Law of Variable Propotion
In the exponential expression a raise to negative n is a positive integer the variable a cannot be equal to zero Explain why this is so?
a^(-n) = (1/a)^nIf a is 0, the above expression would require division by 0, which is not defined.
Explain Single dimensional array concepts C programming?
The idea of an array is to store data for different related items, using a single variable name. The different items are distinguished by a subscript (a number, which may also be a variable or some other expression)

explain development, i need it for homework
