What is called the multiplicative identity for whole numbers and why is it called this?

Why? Because if you multiply (or divide) a number by 1, it remains the same.
eg a x 1 = a
In a similar manner, the additive identity is 0. If you add (or subtract) 0 from a number, it remains the same
eg a + 0 = a.

What are the numbers called to the left of the decimal?
whole numbers
Why is zero called smallest whole number?
Zero is called the smallest whole number because it is the starting point of the number line. It is less than all positive whole numbers and is considered the lowest value in the set of whole numbers. Additionally, zero is the additive identity, meaning that when added to any number, it does not change the value of that number.
What do natural and whole numbers have in common?
They both exclude fractions and irrational numbers. Natural numbers are a subset of whole numbers (also called integers); Natural numbers are any positive whole number (meaning any whole number 1 or greater). Whole numbers, also called integers, can be zero or negative.
What name is given to all the numbers that can be expressed as the sum of two consecutive whole numbers?
It is called a whole consecutive number.
Which set of numbers is also called counting numbers?
Positive integers, (whole numbers) starting at 1
Which is the multiplicative identity for whole numbers?
The multiplicative identity of a number leaves that number unchanged under multiplication. Thus the multiplicative identity of any number is 1.
What do pairs of numbers whose product is 1 called?
They are called multiplicative inverses or reciprocals of each other.
What is the set of whole numbers and their opposites called?
Assuming that you mean opposites (rather than oppisites), the answer will depend on what kind of opposites: additive opposites or multiplicative opposites.In the first case you have the same set as you started with: whole numbers.In the second, you will have the set that consists of the union ofall whole numbers,all unit fractions between -1 and +1. But, you have a problem with zero: its multiplicative opposite is not defined.
What is the multiplicative inverse of a whole number?
Let m be a whole number, then the multiplicative inverse of m is a number n such that mn=1 since 1 is the multiplicative identity. There is only one choice for n, it is 1/m since m(1/m)=1
Is the opposite of each whole number is a whole number?
The answer depends on the context for opposition: the additive inverses are whole numbers but the multiplicative inverses are not (except in the case of -1 and +1).
Is the product of two whole numbers called a multiple?
The result of multiplying two whole numbers is called a product. It is a multiple of each of the whole numbers.
How do you multiplicative an inverse when its a whole number?
The multiplicative inverse of any non-zero integer, N is 1/N.
How do you find the multiplicative inverse of a whole number?
Divide 1 by the number. The multiplicative inverse of 7 is 1/7, for example.
What are numbers called in between whole numbers?
Fractions.
What are the numbers called to the left of the decimal?
whole numbers
What are rational numbers whose square roots are whole numbers called?
Rational numbers whose square roots are whole numbers are themselves whole numbers. They are called square numbers, e.g. 1, 4, 9, 16, 25 and so on.
Why is zero called smallest whole number?
Zero is called the smallest whole number because it is the starting point of the number line. It is less than all positive whole numbers and is considered the lowest value in the set of whole numbers. Additionally, zero is the additive identity, meaning that when added to any number, it does not change the value of that number.
