Real Numbers Review #1

2
The numbers 4, 5, and 6 are called elements. S = {4, 5, 6} When we want to treat a collection of similar but distinct objects as a whole, we use the idea of a set.

3
We do not list an element more than once, because the elements of a set are distinct. If a set has no elements, it is called the empty set or null set. The order in which you list elements in a set is not relevant.

Natural Numbers – N 1, 2, 3, 4, 5, 6, 7, … Whole Numbers – W 0, 1, 2, 3, 4, 5, 6, … Integers – I …, – 2, – 1, 0, 1, 2, … Classification of Real Numbers

5
Rational Numbers Any number that can be written in the form of a fraction. Irrational Numbers Any number that neither terminates nor repeats.

6
Truncation Drop all the digits that follow the specified final digit in the decimal. Rounding Identify the specified final digit in the decimal. If the next digit is 5 or more, add 1 to the final digit. Otherwise leave the number as it appears. Approximations

7
Truncating: 24.748 Rounding: 24.749 Approximate 24.7486 to 3 decimal places by both truncating and rounding.

8
Addition – Sum Subtraction – Difference Multiplication – Product Division – Quotient Mathematical Operations

9
The difference 4 less than x is 12. The quotient of 16 and x is 8. The product of x and 6 is 72.

10
Order of Operations 1.Perform all operations within grouping symbols from innermost outward. 2.Perform all operations with exponents from left to right. 3.Perform all multiplication and division from left to right. 4.Perform all addition and subtraction from left to right.
