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

How distributive and commutative properties can be used to show that two or more expressions are equivalent?
distributive is just a longer way to show the equation and commutative is the numbers combined. Example: 4(5+x) is the distibutive and the equal equation that is commutative is 20+4x
What are some 6th grade math terms?
Dodecahedron= A polyhedron with 12 faces Corresponding= Having the same relative position in similar or congruent figures. Commutative Property= A property at addition and multiplication that says that changing the order of the numbers being added or multiplied dose not change the answer. Truncate= In a decimal, to cut off all digits after the decimal point. Tetrahedron= A polyhedron with 4 faces Addition= Common math problems in which studies show that most 6th graders don't understand as well as multiplication. Subtraction= When the bottem number of a subtraction problem is subtracted from the top number.
How do you use the distributive property and the commutative property to show that 2d plus 4v-3d equals 5v-d?
With a huge amount of difficulty because, as an identity, the equation is false. For example, let d = 1 and v = 1. The equation would then imply that 2 + 4 - 3 = 5 - 1 or 3 = 4 which is patently false.
Why are brackets needed to square negative numbers?
If you were to do -92, following the order of operations, exponents come before subtraction. Because of this -92 = -(92) which is -81. The quantity negative nine, squared, however is positive 81. In order to show that you want the entire quantity negative nine squared, you must use parenthesis (or brackets): (-9)2 = 81. This shows to do the "subtraction" first.
Are the cross products of a proportion equal?
Yes, here's how you can show it, for the equivalent proportions a/b & (n*a)/(n*b): a na -=-- b nb Cross multiply: a*n*b ? b*n*a. Because multiplication is commutative, the question mark is an equal sign.
Give an example to show that subtraction is not commutative?
1-3 != 3-1
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

Give an example to show that subtraction is not associative?
The associative property refers to mathematical expressions where the order of the number is totally interchangeable and will still yield the same answer. Changing the order of a subtraction problem will give you a different answer. For example, 4 - 1 = 3. When switched, 1 - 4 does not equal 3. It equals -3.
Would you please show me an example of commutative property?

Subtraction property of equality?
Will you show an example problem? 5+2=8-1
How do you prove a Ring to be commutative?
To prove a ring is commutative, one must show that for any two elements of the ring their product does not depend on the order in which you multiply them. For example, if p and q are any two elements of your ring then p*q must equal q*p in order for the ring to be commutative. Note that not every ring is commutative, in some rings p*q does not equal q*p for arbitrary q and p (for example, the ring of 2x2 matrices).

Can you give an example to show that division is not commutative?
Two friends & I putted our money 2gether for a road trip. When we got back, we had $45 left. If we split it evenly, how much will we each get? If I divide this way: 45/3=$15 Dividing this way: 3/15=3/15=1/5!
