Just type in the number and hit the +/-   key

9/50

0.18  = 18 / 100  = 9 / 50

(1.8)(-1 2/3)=

(1 + 8/10) (-5/3) =

(1 + 4/5)(-5/3) =

(9/5)(-5/3)  =

(-5/5)(9/3)  =

-1 * 3  =

-3

2(4x-6)+4<4x+4     simplify the left side

8x - 12 + 4 < 4x + 4

8x - 8 < 4x + 4      add 8 to both sides    subtract 4x from both sides

4x < 12      divide both sides by 4

x < 3

x - 3 = 9     add 9 to both sides

x = 12     definitely, a number  !!!!

Thank you!

i believe that it is e³ 

This website is for serious questions only, if you are going to pretend that you dont know that 9 + 10 = 21 than you should just get off the website

(7 + 3/4)  / (1 + 2/4)  =

(31/4)  / (6/4)       invert the denominator and multiply

(31/4) * (4/6)  =

(31/6) * (4/4)  =

31/6   * 1  =

31/6

Here's a website that offers a good explanation with some examples.........

Indeed I do.

I assume this is:

[2] / [ 3 + 2/3]    if so we have

[2/1] / [11/3]     invert the denominator and multiply

[2 / 1] * [3 / 11]  =    6 / 11

3 + [2 *4]  would be correct....we perform multiplication before  addition/subtraction....and we work inside any parentheses/brackets, first......

(45 - 12) / 220    =  .15g   each

Thank you TR for filling in all the gory details :)

I arrived in London this afternoon.  We took the train from the airport to the heart of London.  We alighted at St. Pancras Station.  Our hotel is nearby, we walked,  it was raining of course.  England is famous for its rain.

Anyway I took this photo of the outside of the station this evening.  I like it because you an see the red double decker buses too :)

Use this website it has a great calculator with everything you will need 

6175

I mean just use a calculater. Or use the search bar

-2

yep thats it

4x2x1x0x0-1x0-2

turns into

0-1x0-2

then

0-0-2

0-2

-2

yay

The just look at last question
