Today we discussed about Algebra.. for example.



1) a+1=2

what's happening at the A?

-it is being added by 1.



The next step is,

you make the equation balanced, to make it balanced you put the opposite number beside itself. like this

a+1-1=2



The next step is..

what you did before you have to do it again beside the answer, like this.

a+1-1=2-1



The next step is..

you now subtract 2 and 1 and now you got the answer for this question

a= 1



now you verify..

a+1=2

1+1=2

2=2




HOPE YOU UNDERSTAND IT.(I TRIED MY BEST)

PLEASE COMMENT :)

I PICK CAITLIN FOR THE NEXT SCRIBE.

Decimal numbers such as 3.762 are used in situations which call for more precision than whole numbers provide.

As with whole numbers, a digit in a decimal number has a value which depends on the place of the digit. The places to the left of the decimal point are ones, tens, hundreds, and so on, just as with whole numbers. This table shows the decimal place value for various positions:

Note: That adding extra zeros to the right of the last decimal digit does not change the value of the decimal number.



Im going to show you what we did today but not exactly the same question or number .


Eg. Order these decimal numbers from least to greatest

0.89,0.45,0.27,1.42,1.27

Answer: 0.27,0.45,0.89,1.27,1.42







I pick Edmil for the next scribepost.

Range and outlier

Range- positive difference between the largest and smallest values in a data set.

example:3,9,2,4,7,

First step is ordering them

by smallest to largest

2,3,4,7,9

the smallest value and the biggest value
subtract them together.

9-2=7
* therefor-range is seven


Outlier- a value that is much smaller or larger than the other data values.
- a data set may have more than one outlier or zero outliers.

example: *2,9,7,3,4,108

* 21,24,31,29,23,2,91,24,27
