*Explanation: With all the talk of doubling and halves, your brain jumps to the conclusion that to solve the problem of when the lily patch covers half the lake, all you have to do is divide the number of days it took to fill the lake (48) in half. The problem says that the patch DOUBLES in size every day, which means that on any day, the lily patch was half the size the day before.*So if the patch reaches the entire size of the lake on the 48th day, it means the lily pad was half the size of the lake on day 47.The lessons provide coverage of Levels 1 to 6 of The New Zealand Curriculum.

I read tons of reviews, all with five stars, saying this app saved lives.

To test it, I wrote 2 2 in a shimmery purple jell pen on the back of my hand in the dark (not pitch black but lights off blinds closed in the morning) and it was like oh yeah two plus two is four voilaaaa!!!!! either I died or the world was enchanted with a magical spell cuz I am actually looking forward to doing my homework on Monday. Before I did not get math and I had to get my older sister to tutor me but she will be off to college soon and I will be left tutorless.

What people get wrong here is thinking that because there are only two doors left in play, you have a 50% chance your first choice was correct. There's still a 1 in 3 chance you picked the right door and a 2 in 3 chance you picked an empty door, which means that when the host opened one of the empty doors, he eliminated one of the WRONG choices and the chances that the prize is behind the last closed door is still 2 in 3 — double what the chances you picked the right door at first are.

So, basically, by switching your door choice, you're betting on the 2 in 3 chance you picked the wrong door at first.

before you sit down to actually do it and find you have no clue how to solve it.

## How To Solve The Math Problem Easily

Then there are the problems that make you feel like a math whiz when you solve it in 2 seconds flat — only to find your answer is WAAAAY off.

Some people think that anything a parentheses should be solved FIRST.

Which means they simplify the problem as follows: 6÷2(1 2) = 6÷ 2(3) = 6÷6 = 1.

You pick door #1, and the host, who knows what's behind the doors, opens another door, say #3, and it has nothing behind it.

He then says to you, "Do you want to stick with your choice or switch?
