just use the division bar that's what works best.

5 + 5 = 10

I'm not positive but I don't think you can. play around with it if you find out how then good if not then I don't think it has one.

the sky is blue because of the atmosphere and the way that your eyes perceive light. Blue is the only color reflecting from the sky back into your eyes, therefore, you perceive it as blue

you divide a fraction by taking say your equation is to divide 3/4 by 7/8 so you take your problem and invert the last problem so that you have 3/4 by 8/7 then you just multiply normally. so multiply 3 by 8 and 4 by 7 making it 24/28 then simplify making it 6/7

this is a math forum... it's not a drama forum. therefore really sure you can have freedom of speech... but as long as it's not disruptive... that and if you want to cause trouble go elsewhere because this forum is really for MATH

what's the problem? or a sample of what the problem looks like? I could tell you but I'm not sure what you want to simplify.

going off what ElectricPavlov said I think it's probably easiest to use the divide button because the fraction one never made sense to me.

yep welcome to the forum! :)
