Yeah, ¨Smile More¨ is 100% correct
Smile More is right
if you want to get a 100 listen to smile more
right answer is wrong. you are always going to have a decimal in it when working with this
Smile more is correct.

get your facts straight right answer
lol he is write who we r cheating but i just dont care XD
Smile more is correct, i just took it with the answers and got 100% :)
SmileMore is infinity% correct! :D
HOW do you ALL have 4 QUESTIONS I HAVE 20
1-D
2-A
3-C
4-B
everyone its not that one is wrong its that there is a "a" test and a "b" test not to mention the fact that if you get it wrong the first time the answers will be diffrent the next its how person works sooo i wouldn't argue over such simple things
also it changes on random so there is no code that you can follow the 4rth could change if you got wrong and nothing else it could also just change to its self it all depends on how the code decides
looking deeper into the problem of 2 the answer is A mainly because (of his answers not your own) if you divide a negative you get a negate number so as -2 / 3 is now instead -2 + -3 which is from my knowledge alone since we have similar answers i will try my hardest to find out, but problem 3
i see that its either the exponent of 8 or 12 so its obviously 8 for the reason with two positive exponents with the problem of multiplication is the same thing as division so what you would do is add them together and get 8 for the other part it makes me think what is going on in side of peoples head its not 91.### its 9.1### for how in the hell do you get 91 from 2 and 3? you do not do the multipication in there ill provide a cheat sheet
(if i am wrong with this let me know through messaging me with another program cuz i won't be here once i am done)
multiplication and division you would take the exponent and add them together if the number is a negative you were to in division you would get a negative answer with multiplication its like you were to multiply .5 its still 5 that you multiply its just now you add a decimal to it so with negative -# + -# = -# but instead you multiply also with division to subtraction -# - (-#) = -# + # and the same to the rest of negative. so if you have a negative exponent then the exponent follows the same rule to the other
