Math-->CACAT-ed

Hmmm... I was doing my revision question on PFP, personal financial planning, in case u don't know. and I arrived at this question, asking about the interest rate.

So the calculation is sth like this:

(1 + i) to the power of 5= 5
i = ???

such an easy question and yet I cannot solve!!! wth is happening to my math??? aaarrrgghhhh (bang the wall)

My dinner:
Today I decided to DIY my dinner again. After months of boycotting bread, I finally back to bread again. So the recipe is as below:

1) Keropok Roll inspired by my Cornflake Rolls
-ingredient- bread and keropok, any keropok will do
-method- take a piece of bread, and put some keropok at one side of the bread surface (not too much). Then, you can start rolling the bread together with the keropok in it. Make sure you put enough pressure for the bread to be able to hold the keropok tight.. Ok, you're done.

2) Corns Rolls
-everything is the same except using corns for this one.Make sure u use the ready-to-be-eaten corn rather than the corn for chicken...LOL

Enjoys,
Chef Joseph.
