Is set notation better than interval notation?
Depends on the context. When you’re talking about subsets of the reals that are in an interval or a union of intervals, then interval notation is better. But for subsets of the reals that just satisfy a property (e.g. the set of numbers that are prime), then set notation is better.

What is "extended notation" in math?
Expanded notation is the term given in elementary mathematics education for the expansion of a positive integer in the form , i.e., as a sum of appropriate powers of 10 (the base of the expansion) times its digits (in the case of base-10, decimal digits).

What are the two methods of multiplying numbers?
There are two methods of multiplying the numbers, namely the expanded notation method and the column method.
What is Multiplication?
The process of finding out the product between two or more numbers is called multiplication. The result thus obtained is called the product. Suppose, you bought 6 pens on one day and 6 pens on the next day. Total pens you bought are now 2 times 6 or 6 + 6 = 12.
What is the associative property of multiplication?
Associative Property states that when an operation is performed on more than two numbers, the order in which the numbers are placed does not matter. In the case of multiplication, this means that if we want to multiply 3 numbers, two of them can be chosen first, one as a multiplier and the second as a multiplicand. The result of the multiplication would serve as a multiplier and the third number as multiplicand to get the final answer. Is multiplication associative? Let us find out.
What is the number to be multiplied called?
Multiplicand – The number to be multiplied is called the multiplicand.
What is the multiplicative inverse of a number?
A number is said to be multiplicative inverse if a number is multiplied by the multiplicative inverse, the result obtained is the identity of the operation, in this case, 1 ( 1 is the multiplicative identity of all numbers).
How to multiply by 10?
To multiply a number by 10, put 0 to the right of the number. For example, 435 x 10 = 4350
What is the commutative property of a number?
Commutative Property states that when an operation is performed on two numbers, the order in which the numbers are placed does not matter. This means that if one number is multiplied with the other, it does not matter which number is marked as the multiplier and which number is marked as the multiplicand. Does this hold true for multiplication? Let us find out.
