I guess it's sort of a number sense mentality to want to problems faster rather than with accuracy and ease...

Academic U.I.L. is fine ingrained within my mind now.

u mean BJ? LOL

Yep...me, too.....HappyBJ.....!!!

thanks, M!!! (we need to find a nickname 4 ur profile name...its too long!! LOL)

I was thinking the web2.0calc was the one being used, you are correct about about the TI line button placement HappyBJ.

i like the method. it seems kind of easier lol..

It is definitely very accurate because of its display; however by "going down the line" in distribution, one can combine like terms in the same way.

It is a good method for teaching, but in practice, I use distribution.

Thanks for both those answers, guys.....!!!

if u have a t-83 or ti-84 calculator, u would push "Stor->" near the bottom left. :)

I dunno'...this method seems pretty "clean'.....you can follow the "diagonal" pattern to combine like terms......!!!

Just type it in: it's shift key 6. To avoid clutter, ask questions on your previous question.

Yep, it's the first method my school taught me (just recently), but using distribution is less time consuming.

V = L x W X H

Yes, I already said that TBOY1. Beides it is 0.818181...

It continues to repeat. It is a repeating decimal. But in the context of the question, a fraction answer was more probable.

A lot of school calcs have fractions buttons and you can reduce fractions with it easily.

How this is done depends on the calc.  

 it is (7/11)+(2/11)=.81 or  9/11

Just type: "10^8"

Just type: "3 * 10^8"

Mistype...

this post might help you

Thanks, Mathematician....I like that method !!!

When adding fractions with the same denominator, just add the numerators together: 7 + 2 = 9, so 7/11 + 2/11 = 9/11.

there is a toggle button down the bottom of the calc to put it into degrees or radians.

When typing, use this notation for power "^2"

So we have:

(2x + 1)(3x^2 - 2x - 5)

Let's use the box method of multiplication for explanation:

       3x^2    -2x      -5    

2x | 6x^3 | -4x^2 | -10x

1   | 3x^2 | -2x     | -5

Since we've multiplied all of the terms using a box, now we can add them all together:

6x^3 + 3x^2 - 4x^2 -2x - 10x - 5

After combining like terms, we have: 6x^3 - x^2 -12x -5

Your brackets are unbalanced but this is what I have interpreted.

$$\\\sqrt{\sqrt{3+1}^2+(3-1)^2}\\\\
=\sqrt{\sqrt{4}^2\;\;+\;\;(2)^2}\\\\
=\sqrt{4+4}\\\\
=\sqrt{4*2}\\\\
=2\sqrt{2}\\\\$$
