How to solve/check equations
12=12 (normally there would be a check mark above the equal sign)
x=7
7=y-5
7=12-5
7=7
y=12
Multiplication and division are a little bit more difficult.
3z=12 (3z is 3 times z)
3x4=12 (Instead of an "x" to multiply, a dot would be there)
12=12
z=4
Division
v divided by 3=4 (Normally a division problem would be written like a fraction)
12 divided by 3=4
4=4
v=3
It is very complex to do, so be very careful on how you do it. Now it is time to solve equations. Solving equations are very, very hard at first. Just do not confuse the solve with the check. This can cause you to get the wrong answer. Solving is just doing the opposite operation of a number. These are examples of solving problems.
x+10=17
-10 -10
x=7
Subtraction
y-12=5
+12 +12
y=17
Multiplication and division are hard to solve with. These are a couple of examples of those operations.
8v=16
divided by 8 8(supposed to be centered)
v=2
Division
v divided by 8x8= 2x8
v=16
(bold means work for this problem)Hard at first, but a little bit easier along the way. This is very important to do later on. This is a few vocabulary words that are very important.
Variable-a random number, usually represented by a letter. x+5=9
Operation-addition, subtraction, multiplication, and division. +, -, x(this is a basic multiplication sign, but in problems it is written as a dot), (there is no division sign, but a basic division sign would be a minus sign with two dots above and below it. Normally written as a fraction.)

Factors and Greatest Common Factor (GCF)
80
10 8
5 2 2 4
5 2 2 2 2
(To make the primes look better, make the most shown number and make it into exponents to make it look like this, 5 x 24)Pretty easy once you know it well. Now I will teach you how to do the GCF, or greatest common factor. The greatest common factor is the greatest common factor between two or more numbers. Pretty confusing, but it should look like this.
List all factors of both numbers
24:1,24,2,12,3,8,4,6
48:1,48,2,24,3,16,4,12,6,8
GCF:24
or
24
48:1,48,2,24,3,16,4,12,6,8
Take the biggest number and find the factors of that number.
Then see if the biggest factor goes in the other number(s)
Quite simple if you know your multiplication. Here is some key vocabulary.
Factor: A multiplier that multiplys another number.
Prime Factorization: Taking a big number and finding the prime factors.
Greatest Common Factor: The greatest factor shared between two or more numbers.
For more examples or problems on how to do GCF, go to http://go.hrw.com/math/midma/gradecontent/loadlesson.html?course=c2&chapter=2&lesson=5&SE=1&sz_audio=1&calc=1&state=xx&actCourse=0
For more examples or problems on Prime Factorization, go to http://go.hrw.com/math/midma/gradecontent/loadlesson.html?course=c2&chapter=2&lesson=4&SE=1&sz_audio=1&calc=1&state=xx&actCourse=0
For reasons why to do Prime Factorization, go to http://www.mathmojo.com/interestinglessons/why_learn_prime_factors/why_learn_prime_factors.html
(I would use a link to show you why GCF is used, but there are no examples, sorry)
Both very simple, but very hard if being used on bigger numbers. See you later!

How to do Exponents
33=27
(Sorry , I couldn't get the exponent in the right place, but the exponent should be in the top right corner next to the number) Anyways, you multiply the number by the exponent. It's pretty simple once you get the hang of it.
The base is the main number which gets multiplyed by the exponent. The exponent is the number that multiplies the base. For an example click here, http://go.hrw.com/math/midma/gradecontent/loadlesson.html?course=c2&chapter=2&lesson=1&SE=1&sz_audio=1&calc=1&state=xx&actCourse=0
