Prime factorization is like the prime number are the basic building blocks of all numbers .
x
x
When your trying to find your answer in prime factorization your answer will be all prime numbers, In the example i gave all prime numbers are 2,3,3 so your answer will be 2x3x3 but 3x3 can be written in exponent.So your answer is 2x3 to the 2nd power
When your doing Order of operation you need to do it in order so the order is this way.
Third step is to subtract 300-4 because subtracting gose last.
First step is going to be (5x50) because we do Parentheses.
HINT:START IN ORDER FROMLEFT TO RIGHT
Second step is add 250+50 because adding gose first than subtraction.
EXAMPLE:
When you want to find out the answer for this problem you need to multiply 5 three times like this 5x5x5.We do this because the exponent is 3 so we have to show three times the 5 so,5x5x5=125
Base
5x5x5 25x5 125
(The number that is multiplied)
Exponent
Exponent tells us how many times to multiply the base
EXAMPLE:
When your Modeling Equations you can use bar models like i did.
Modeling Equations is when you are modeling a equation like this.
7+x
7
X
EXAMPLE:
x-9;x=15 x-9=15-9-6
Before you do something you need to know the value of the variable.
HINT:BE CAREFUL HOW YOU RE-WRITE IT!
When you are Evaluating Expressions you are finding the value of the variable like in this example x=15 so we re-write the problem now the problem is 15-9=6 .
EXAMPLE:
When your Generating Equivalent Expressions you need to see if the two expressions are equal to the same answer, like the example i put it says 5(3)+65=5(3)+1 if your asking how to do this you need to solve the problem.
First you have to multiply 5x3 for both examples that will be 15.
5(3)+65=5(3)+1
15+65=15+1
80=16
For this problem there not equivalent .
Second step is to add 15+65 for List A that will be 80
Third step is to add 15+1 for List B that will be 16
One way to test whether two expressions might be equivalent is to evaluate theme for the same value of the variable.
Last step is to see the answer you have and see if its the same answer.
