A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the commutative property of multiplication?

An operation is commutative if you can switch the operands and get the same result. That is, ! is commutative if (and only if) a ! b = b ! a. For example, multiplication of integers is commutative: 17*42 = 42*17 = 314, for example. Subtraction is not: 17 - 5 = 12, but 5 - 17 = -12.When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example 4 * 2 = 2 * 4

Give an example to show that subtraction is not commutative?

1-3 != 3-1

What is an example of subtraction of integers?

Integers are whole numbers as for example 28 minus 17 = 11

Give example of communitative property of integers?

That's commutative ... 3x2 = 2x3.

Explain if the commutative property of addition applies when you add two negative integers?

The commutative property holds for all numbers under addition, regardless of whether they are positive or negative - the sign of the number stays with the number, for example: -2 + 5 = (-2) + 5 = 5 + (-2) = 5 + -2 -2 + -5 = (-2) + (-5) = (-5) + (-2) = -5 + -2 Subtraction is not commutative, but when subtraction is taken as adding the negative of the second number, the commutative property of addition holds, for example: 5 - 2 ≠ 2 - 5 but: 5 - 2 = 5 + -2 = 5 + (-2) = (-2) + 5 = -2 + 5

Can you give an example to show that subtraction is not commutative?

5 - 3 = 2 3 - 5 = -2 2 is not the same as -2 so the operation is not commutative.

What is commutative property of subtraction?

Commutative means things can move or commute. For example A+B=B+A But A-B does NOT equal B-A. The example A+B=B+A is an example of the commutative property of addition. More formally: An operation is commutative if you can change the order of the numbers involved without changing the result. Subtraction does NOT have a commutative property because you cannot change the order. Here is one last concrete example. 5-4=1 and 4-5 =-1 If you know about absolute value, then you might know that |5-4|=|4-5|=1 and in general |a-b|=|b-a|, but this does not mean that subtraction commutes.

Does the commutative property of addition apply when you add to negative integers?

Yes. The commutative property of addition (as well as the commutative property of multiplication) applies to all real numbers, and even to complex numbers. As an example (for integers): 5 + (-3) = (-3) + 5

Give an example of why subtraction is not commutative?

commutative means the numbers can be put in a different order and equal the same thing such as 3+4=7 and 4+3=7. the subtraction problem 7-3=4 is not commutative because if u switch the 3 and 7 the equation is 3-7=-4. the numbers are in a different order but you dont get the same answer so its not commutative

Does it matter when using subtraction the order in which the numbers are presented?

Yes it matters. Subtraction is not commutative. Example: 5-2 = 3 (positive three), but 2-5 = -3 (negative three)

Is subtraction commutive?

No.The binary operation of subtraction (really adding a negative number) is NOT commutative.Let's say * is the binary operation of subtraction (really addition): such thata*b = a - b or more correctly: a + (-b).Let's assume it is commutative, Then a*b = b*aLet's find any counter example to show that this not the case:a=1b=41 + (-4) =/= 4 + -1-3 =/= 3

How does knowing the commutative property cut the number of facts to be learned in half?

The above is only partially true since not all mathematical operations are commutative. For example, subtraction is not commutative (though addition using negative numbers is). Where an operaton is commutative it does halve the number of facts to be learned. For example, when you have learned 2+3 = 5, you do not need to learn 3+2.
