-61 – (83 – |-91|)

= -61 – (83 – 91)

= -61 - 83 + 91

-61 -83 + 91 = -53

period = 2pi/(2pi) = 1

They just said that Omi accidentally used 0.25 instead of 25 in here first substitution. :/

What do you mean ?

Hi Ginger :)

The rules are the same - what is your question?

Here is your REAL cake ...

Now you have 2 cakes that you can share with everyone on the forum :))

I messed that one up - Sorry Rosala.     

Do what?

log(x) + log(y) = log(z)

\(\begin{align} log(x) + log(y) &= log(z)\\ log(xy) &= log(z)\\ xy&=z\\ z&=xy \end{align}\)
