2 x 6 = 12 2 x 2 x 3 = 12
2 x 6 = 12 2 x 2 x 3 = 12
Using the communative property of both addition and multiplication, 11+ab could be rewritten as ab+11, 11+ba or ba+11.
The associative property of a binary operator denoted by ~ states that form any three numbers a, b and c, (a ~ b) ~ c = a ~ (b ~ c) and so we can write either as a ~ b ~ c without ambiguity. The associative property of means that you can change the grouping of the expression and still have the same result. Addition and multiplication of numbers are associative, subtraction and division are not.
1. Write equation on paper. 2. Use Distributive Property. 3. Combine like terms. 4. Use reflexive Property. (ex.- adding or subtracting 3x to both sides) 5. Inverses Property of Addition ( answer; almost to final answer) 6. Reflexive Property. (ex.- add or subtract 2 to both sides of equation) 7. Inverse Property of Addition (ex.- 5x=5) 8. Multiplication Property (ex. 5x/5= x=1 OR (1/5)(5x) = 1/5(5)= x=1 9. Final answer (ex: x=1)

The commutative property for addition is a + b = b + a
The Associative property of multiplication states that the product of a set of three numbers is always the same no matter which operation is carried out first.For example Ax(BxC) = (AxB)xC and so either can be written as AxBxC.ie 3x(4x5) = 3x20 = 60and (3x4)x5 = 12x5 = 60It is important not to confuse this with the commutative (or Abelian) property which states that the order of the numbers does not matter. ie AxB = BxAMatrix multiplication, for example, is associative but NOT commutative.(a * b) * c = a * (b * c)As a result, we can write a * b * c without ambiguity.
it can be used to write a multiplication sentence by flipping the numbers around
no just write zero. or maybe like an example 2x0=0
Because multiplying is the inverse of dividing
7r = r + r + r + r + r + r + r or r7
Mainly the commutative property. But the fact that 30*8*7 is unambiguous and you do not need to write (30*8)*7 or 30*(8*7) is due to the associative property.
hi
The commutative property states that given any two numbers, x and y,x + y = y + xThe property applies to all real numbers and complex numbers as well.2.3 + 4.5 = 6.8 = 4.5 + 2.3
The sum of b and 8 would be written b+8 or 8+b(commutative property of addition)
The associative property of multiplication states that for any three numbers a, b and c, (a * b) * c = a * (b * c) and so we can write either as a * b * c without ambiguity. The associative property of multiplication means that you can change the grouping of the expression and still have the same product.
