8.01 x 10²³

.000064

in that order? 156

using order of operations? 33

there are, of course, fractions.

in this case, you enter x/y         ex. 1/2  =  .5

be careful when plugging them into the calculator though, because the calculator goes by the Order of Operations. 

so if you are trying to do 4 times 9/3, and entered it as 9/3*4, you wouldn't get the right answer.

parenthesis are friends!!!

(9/3)*4 is correct

2.334476386 / 354.00001 x 36442 = (unneccessary 2nd =) 240.3191696480791874.

but im sure you all ready knew that

20% of $900 = $180

45% of $900 = $405

180 + 405 = 585

so subtract from the original total (900) and...

 = $315

i went the long way to show steps, the shorter way would be to take 35% of $900. 

i can't explain your first question other than people think they're funny and want attention...

but as for using the Pythagorean Theorem, you should be given 2 of the unknown variables: a, b, or c ***

a² + b² = c²

so if you have a and b, b and c, or a and c, you can plug the numbers in, square and subtract, and get the third term.

*** if you don't have 2 given variables, look at the diagram or question and try to find them

there's a tab at the top of the screen that says Home

Hey how about using a calculator?

1/4 x 125.60 = 157/5 = 31.4
