What is an algebraic expresion?
an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication,division and exponentiation to a power that is a rational number). For example,
What is an inverese in algebra?
An inverse is another word for opposite. The inverse for adding is subtraction, multiplication is division, etc. If you are solving an equation, and have to get a variable alone, you must eliminate any other numbers with the variable, which means undoing the operation (x, +, -, /); so you perform the inverse. Example: x + 3 = 9. Subtract 3 on both sides to get x alone, because subtraction is the inverse of addition: x = 6. Example: 2x + 3 = 9. You must do the inverse of addition and subtraction before the inverse of multiplication and division. In this case, after subtracting 3 you have: 2x = 6. x is being multiplied by 2, so the inverse is division, and your answer is x = 3.
What is the result of multiplication?
The result of a multiplication problem is called a product.
Why does the commutative and associative properties don't hold true for subtraction and division but the identity properties do?
Consider the main operations to be addition and multiplication. In that case, subtraction is defined in terms of addition, for example, a - b = a + (-b) (where the last "-b" refers to the additive inverse of b), while a / b = a times 1/b (where 1/b is the multiplicative inverse of b). Now, assuming that commutative, etc. properties hold for addition and multiplication, check what happens with a subtraction. That should clarify everything. For example: a - b = a + (-b) whereas: b - a = b + (-a) which happens NOT to be the same as a - b, but rather its additive inverse.
Is divsion associative?
Division (and subtraction, for that matter) is not associative. Here is an example to show that it is not associative: (8/4)/2 = 2/2 = 1 8/(4/2) = 8/2 = 4 Addition and multiplication are the only two arithmetic operations that have the associative property.
Operation of fraction?
I'm assuming you're asking if a fraction is addition, subtraction, multiplication, or division? If so, it's division. For example, 1/2 = 0.5.
PEMDAS is what?
The order of steps you take in a math problem Parentheses, Exponents, Multiplication, Division, Addition, Subtraction For Example: (2x3)+20-2x5, if you follow pemdas the answer is:16
What properties do the distributive property work for?
addition and subtraction * * * * * No. The distributive property applies to two operations, for example, to multiplication over addition or subtraction.
When simplifying an expression you perform which operations inside grouping symbols first?
Within parentheses or similar symbols, the same rules apply as when you don't have parentheses. For example, multiplication and division have a higher priority (or precedence) than addition and subtraction.Within parentheses or similar symbols, the same rules apply as when you don't have parentheses.

What is given highest priority in Excel multiplication division subtraction or addition?
Multiplication will be given equal priority and will be done on a left to right basis. So for example, the multiplication would be done first and the division second in the first example and the division would be done first and multiplication second in the second example, with the addition being the last thing to be done in both examples: =A3+A4*10/7 =A3+A4/10*7
Can you apply the associative property to subtraction?
No, the associative property only applies to addition and multiplication, not subtraction or division. Here is an example which shows why it cannot work with subtraction: (6-4)-2=0 6-(4-2)=4
What is the example of binary operator?
There are many: addition, subtraction, multiplication and division are the most common. Each of these operators acts on two numbers to produce a third (which may not be different).
What operation should be done first in an Excel expression?
If there is any, the power of is done first, like 10 squared for example. It can be more complex than that, when you bring other elements into calculations. BOMDAS is a way of remembering the order to do things in: Brackets, power Of, Multiplication, Division, Addition, Subtraction. There are other variations of this: Parantheses, Exponentiation, Division, Multiplication, Addition, Subtraction.
Why addition and multiplication are easier than subtraction and division in computer?
Well, actually, division is just multiplication in reverse. Take 21 divided by 3 for example, and 7 times 3 is 21, so 7 is the answer for division. Try some new numbers and you'll get it! I've mastered division, so will you.
Why isn't there an identity property of subtraction?
Because you can do the same with the Identity Property of Addition. Here's an example: 5 + 0 = 5 5 - 0 = 5 The same goes for multiplication/division.
Positive and negative what is the final result?
It depends on the operation and values of the positive and negative. For example, in multiplication or division a positive and negative will be a negative. In addition or subtraction, it depends on the absolute value of the original numbers.
