Haha, after the first year I totally forgot the forum at about 450 points, then I started going on and soon enough, I got tons of points.

There are people that get 50-100 points a day, I'm sure you can get tons in no time!

Yes, I'm pretty sure stars = points.

I'm not sure, you've actually been on a lot longer than me, too.

If the numbers' sum is 8, they can be...

1 and 7

2 and 6

3 and 5

4 and 4

I assume we are going to the negatives, though, there is no number that has a difference of 14 here.

-3 and 11 have a difference of 14 and a sum of 8, therefore...

The two numbers you are looking for are...

-3 and 11

That would be correct if Guest asked "what is the fourth root of 81."

However, he/she asked what squared root to 4 is 81.

Wouldn't that technically be 81 * 81 * 81 * 81 = 43,046721?

Maybe Guest meant "what squared to 4 is 81."

GOOD MORNINGG!

Or for some people good afternoon.

THANKS, MATHFORDAYS!

*gasps*

You don't mean...

-dun dun dunn-

Five days?!?

30 + 30 + 30 + 30 + 30 + 30 + 30 = 30 * 7 = 210

To be fair, 4 days is quite an achievement!

Let's use order of operations (PEMDAS)...

2^3 - 8 / 4 x 2 + 7

First, solve the exponent (E in PEMDAS as there are no parenthases).

2^3 = 2 * 2 * 2 = 8

Now we have 8 - 8 /4 x 2 + 7.

Next, multiply/divide (whichever comes first left to right).

8/4 = 2

8 - 2 x 2 + 7...

2 x 2 = 4

8 - 4 + 7

Now, add/subtract (again, left to right).

8 - 4 = 4

4 + 7

18 / 1 1/2

First, change 18 into a fraction.

18 = 18/1

So...

18/1 / 1 1/2

Next, make 1 1/2 an improper fraction.

1 1/2 = 3/2

Now we have...

18/1 / 3/2.

Next, use "keep, change, flip."

Keep 18/1...

Change 3/2 into its reciprocal...

18/1 / 2/3...

Flip the division sign into a multiplication one.

18/1 * 2/3

Now, multiply each numerator by the other and vice versa for the denominators to get your answer.

18 * 2 = 36

1 * 3 = 3

36/3

Simplify...
