DISTRIBUTIBE PROPERTY

ReplyDeleteWhat i learned about the distributive property is that you can use it for all orperations.

For example, you could do 8(5+4) or 5(17-8)

TOP ONE IS BY JAMES

DeleteMy topic is Order Of Operations. I learned that you always have to use the technique PEMDAS. What I mean by that is: It stands for Parentheses, Exponents, Multiplication or Division, Addition or Subtraction. Whenever your doing a problem with parentheses or an exponent you always have to do it this way. Remember to do it in the order PEMDAS. That is what I learned doing the Order Of Operations. Here Are Some Examples:

ReplyDelete8+{10-3}+ 39= Answer: 54

30+99-{43+78}= Answer:18

Properties review

ReplyDeleteI learned that you have to use subtraction to solve a multiplication or division equivalent problem in algebra.

Example:

24 x 32 = (24 x 25) + 24 x _ (you would have to find 32 - 25)

- Alison

Equations with Variables:

ReplyDeleteI learned that variables can be confusing because they are letters but, the letter is basically blank or box.

Example: 4+n=10 which is the same as 4+_=10

-Anika

Identity property of 0 : I know that any number times 0 will = 0. Example: 76x0=0

Commutative Properties of Addition and Multiplication

ReplyDeleteI learned that in order to do the commutative property, you have to basically switch around the placement of the numbers. Meaning that even with parentheses, just switch it around!

Example: (23x42)x9=(42x9)x23

ReplyDeleteOrder of Operations:

ReplyDeleteI learned that you have to do PEMDAS. It stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. Do it in that order or your answer may be wrong. Here are some examples:

3+{3x3}+5 Answer: 17

3x9+{4+5}+1 Answer: 37

Identity Properties and Multiplication by Zero:

ReplyDeleteI learned that when you multiply a number by one it will always be the number it is being multiplied. Also I learned that when you multiply a number by zero it will always be zero no matter what.

Examples:

54x1=54

64x0=0

- Sudeep

Order of operations:

ReplyDeleteI learned what PEMDAS is.That is P for parenthesis, E for exponents, M for multiplication, D for division, A for addition, and S for subtraction. It has to be done in order or the answer will be incorrect.

Forgot example. Examples:

ReplyDelete2x(12- 27/3)+7=13

Identity Properties and Multiplication by Zero:

ReplyDeleteI learned that when you multiply numbers and then it is x 0 that it will always be zero.

Example:

8739 x 6382 x 0= 0 -Shannon

Equations with variables

ReplyDeleteI learned that variables can be any letter in the alphabet but they cannot be a symbol . N x 6 = 12 N = 2 Duncan

I used equations with variables. I learned if it tells the answer and the first number you can guess the variables. 17+x=20 x= 3.

ReplyDeleteThe topic that I used is Expressions using parentheses. I leaned that if there is ever a set of parenttheses you always do that problem first before the others because if not you will get the wrong answer. Example: (7x2) + 11 - 8 =17 - Lex

ReplyDeleteEquations with variables

ReplyDeleteWhen there are variables you usually try to figure out what it stands for. Example: 5g=35 DJ

I used Expressions using Parentheses

ReplyDeleteFor example....

(8x4) + (5x6)

8x4=32 5x6=30 30+32=62 this is from EMMA

Expressions using parentheses. I leaned that if there is ever a set of parenttheses you always do that problem first before the others because if not you will get the wrong answer. Example: (7x2) + 11 - 8 =17 - Lex

ReplyDeleteI used equations with variables. I learned if it tells the answer and the first number you can guess the variables. 17+x=20 x= 3. Andrew

ReplyDeleteOrder of operation. i learned that you have to do the algebraic expression in the correct order of operation in order to get the right answer. Example:34-b+(9+8)=49.

ReplyDeletemegan.

I learned that PEMDAS always go in order ex; 3*4(9+11)=32 is the real answer
