Upgrading Adult Advancement Campus - ONLINE
Welcome to Week 1 Math! You will find the math pages very different from the English pages. Each section will have a question and answer page and designed to print. If you have any difficulty with a problem you can call, e-mail or attend a class; times listed in the calendar. Enjoy! This is going to be a blast!
Take a guess! During our adult memory class we learned that it's a great idea to get our brain's thinking about information before we start. By asking ourselves questions before we learn the answers we not only challenge ourselves, but we learn that it is okay to take a guess. We are checking our brains ahead of time to see what we have retained. We may be wrong but that's okay! That means we need to relearn the correct information. We need practice in guessing. IT'S OKAY TO GUESS!
Before we talk about prime let's review odd and even numbers. Even numbers are all the numbers that 2 can go into. 2, 4, 6, 8, 10, 12, 14, 16, 18,20, 22, 24, 26, 28, 30, 32, and so on. Odd numbers are the ones inbetween the evens including the number 1. 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33 and so on. Prime numbers are almost always odd. Prime numbers are the odd numbers where you can't divide or multiply numbers into them. For instance: 3 X 5 = 15 15 is an odd number, but you can times 3 and 5 and get 15 or divide 15 by 3 or 5. 15 is an odd number but not a prime number. How about the number 17. Nothing goes into it EVENLY except the number 17 and 1. The number 17 is a prime number. 17 divided by 17 = 1 17 divided by 1 = 17
1 x 1 = 1 1 x 3 = 3 1 x 31 = 31
Some prime numbers: 1, 3, 5, 7, 11, 13, 17, 19 23, 29, 31 33 is not a prime number because 3 X 11 = 33 31 is a prime number because the only two numbers that can go into it are 1 and 31 1 x 31 = 31
Natural numbers are all the counting numbers except for 0 zero. Natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,1 4, 15, 16, 17, 18, 19, 20, 21 and so on.
Whole numbers are all the counting numbers AND 0 (zero). Whole numbers 0, 1, 2, 3 ,4, 5, 6, 7, 8, 9, 10, 11, 12, and so on.
An easy way that I remember is the the word "whole" has an "o" in it which reminds me of zero. Whole numbers include zero.
The whole numbers and natural numbers above are also called "positive" numbers. There are also negative numbers. (We will be going over negative numbers more in week 11) The way I look at negative numbers is what we owe. A bill from the electric company is what we owe. If we owe $28.00 that's a -28. Integers are all negative and positive numbers including 0(zero).
.... -5, -4, -3, -2, -1 1, 2, 3, 4, 5 ….
Rational numbers are all the numbers that are fractions. 1/4 1/3 -8/19 Here's a more "mathy" definition: "a number is rational if we can write it as a fraction where the numerator and denominator are both integers." http://mathforum.org/dr.math/faq/faq.integers.html
I prefer the first definition. You pick the one you like.
If you are going on in math, the second definition might be important to understand and remember.
These two words have to do with a fraction. The top number in a fraction is called the, "numerator." The bottom number in a faction is called the, "denominator." That's all it is! Fancy math words for the top and bottom of a fraction.
The denominator tells us how many pieces we cut the pizza into. The numerator tells us how many pieces are left or how many we have eaten.
The denominator in this example would be 4. The pizza is cut into 4 pieces so the denominator is 4. How many pieces were eaten? One piece was eaten. The numerator is 1. The answer is 1/4. How many pieces are left? The denominator stays the same because that's how the pizza was cut; into 4ths. How many 4ths are left. Three. The numerator would be 3. The answer is 3/4ths of the pizza is left.
This may not seem a lot for week 1, but it is important that you remember. Throughout the week go over this each day. After the third time, test yourself. After the first week, click on this link once a week until you are finished with the program. Even if you are working on English for two weeks do not skip coming back to this page once a week.
6 ∙ 2 = 12
I don't why they didn't tell us in 2nd grade that this was a division symbol. All they told me was that it was a fraction.
When there is not symbol in between the number and the paraenthases; that's multiplication! WHO knew???
... the dot is the same as a times; they use it more with algegra problems
