What is mathematical sequence?
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
What is a group of related multiplication and division facts that use the same numbers?
array
Do positive rational numbers form group?
Yes, with respect to multiplication but not with respect to addition.
What is the additive inverse of 9.1?
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.
Is the group of all real numbers except 0 under multiplication is an infinite group?
s

What is inverse in math terms?
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.
Example of group is an abelian group?
The set of integers, under addition.
Do positive rational numbers form group?
Yes, with respect to multiplication but not with respect to addition.
What is the identity element for addition and subtraction?
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.
What does commutative mean in math?
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.
What is the answer for 7 plus 14 -3 plus 5x2x2x2?
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
What is the property of associative properties?
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]
Why do we start from addition and substraction when learning math?
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.

Why the set of rationals does not form a group wrt multiplication?
All the elements in a group must be invertible with respect to the operation. The element 0, which belongs to the set does not have an inverse wrt multiplication.
