Sequences are a group of numbers that follow a certain pattern. There are two kinds of sequences, the arithematic sequence and geometric sequence. Arithematic sequence follows through addition (and subtraction). Geometric sequence follows throug multiplication (and division). Arithematic Sequence Example : 1, 6, 11, 16, 21 The pattern follows an addition of 5. Geometric Sequence Example : 1, 3, 9, 27, 81 The pattern follows a multiplication of 3

Yes, with respect to multiplication but not with respect to addition.
We are talking group theory here. A group with addition has an additive inverse. A group with multiplication has a multiplicative inverse. The additive inverse of a number x is a y with x + y = 0. The additive inverse of x is written -x. Hence, the additive inverse of 9.1 equals -9.1. The reason that this question can arise is that beyond groups, there are rings and fields. Rings and fields have, besides addition, also multiplication. An element can have an additive inverse and a multiplicative inverse at the same time.
No. The inverses do not belong to the group.

In maths, the term there are two main meanings to the word inverse - both of which are very closely related. Simple answer in the last three paragraphs. A binary operation, defined on a group of numbers is a rule that tells you how to combine two numbers to get a third. Each binary operations (@) has an identity element, generally denoted by i, such that: x@i = x = i@x for all x in the group. Then, for each element x, there is an element in the group, denoted by x-1 (or the inverse of x) such that x@x-1 = i = x-1@x All this may sound rather technical. So here it is in simpler terms: two everyday examples of binary operation are addition and multiplication. The identity for addition is 0. The identity for multiplication is 1. The inverse of x, under addition, is -x. Under multiplication it is 1/x (not defined for x = 0). These give rise to inverse binary operations: subtraction for addition and division for multiplication.
The set of integers, under addition.
Yes, with respect to multiplication but not with respect to addition.
0, zero, is defined as the identity element for addition and subtraction. * * * * * While 0 is certainly the identity element with respect to addition, there is no identity element for subtraction. The identity element of a set, for a given operation, must commute with every element of the set. Since a - 0 ≠ 0 - a, according to group theory, 0 is not an identity with respect to subtraction.
involving the condition that a group of quantities connected by operators gives the same result whatever the order of the quantities involved, e.g., a × b = b × a . THis works for addition as well a + b = b + a but not for subtraction or division.
Multiplication and division are always done before or seperate to subtraction and addition, so we will bracket them into their own group:7 + 14 - 3 + 5 x 2 x 2 x 2(7 + 14 - 3) + (5 x 2 x 2 x 2)(21 - 3) + (10 x 2 x 2)18 + (20 x 2)18 + 4058
The ASSOCIATIVE property states that the order in which the binary operation denoted by ~ is carried out does not matter.Symbolically, (a ~ b) ~ c = a ~ (b ~ c)and so, without ambiguity, either can be written as a ~ b ~ c.Addition and multiplication are common operations that are associative. Subtraction and division are not.Associative Property; * use of parenthesis it doesn't matter ho we group numbers to get and an sub [total\amount]
The grouping property, also known as the associative property, states that the way in which numbers are grouped in an arithmetic operation (addition or multiplication) does not affect the result. For addition, (a + b) + c = a + (b + c). For multiplication, (a * b) * c = a * (b * c).
Addition and subtraction are the core to most math. Even Children who don't know math can add and subtract. Addition is the mathematical concept of putting things together to form a greater amount. Subtraction is the opposite. Subtracting one thing from another is the same as taking some things away from a group. So the children can know how much they got compared to others and how much has been taken from them.
