Couple of sums for you

[mufc802]

10.1 - 1.1 - 1.01 = 7.99 = 8. More 0's the closer it gets.

1000.1 - 11 - 0.11 = 988.99 = 989.

101 - 101 - 101 = 9080090

101 - 101 - 101 = 800

lol lol lol go boo go

sorry, i blame red wine

 

[kPATm]

My head really hurts

 

[Greebo]

zeros missing from the answer as well?

 

[kPATm]

No I dont think so. There are about 30 questions all together and we have managed to get everyone but these 2 and all the other answers dont have a missing zero

[semi-pro waster]

It doesnt actually mention anything about decimal places in her homework but as long as the answer is

989 for the 1st

8 for the 2nd

then I dont see why not

Does it mention rounding or has it involved rounding in any other question? If it doesn't then I'd tend to think that it isn't allowed.

Although I've got to admit I'm not getting any closer to the answer than 988 for the first just using whole numbers with zeros inserted into the sum.

 

[danza]

First one is:

1001-11-11^0=989

Second is:

110-101-11^0=8

 

[Will Gill]

forgive my obvious ignorance, what does that symbol mean? I only did a-level maths and I know I've drunk and smoked my brain into submission since then but I don't recognise it!

 

[kPATm]

Yip what does the ^ mean?

 

[danza]

^ = to the power of.

Anything to the power of zero = 1.

 

[kPATm]

Remember this is homework for a 12year old so I wouldnt expect the answer has anything to do with advanced mathematics

 

[rogan]

to the pwer of

 

[kPATm]

Ha it is correct Yoda

 

[Will Gill]

ahh, cunning, well done I'll dispose of the huge amount of useless calculations scribbled on my notepad

 

[kPATm]

So is that something 12 years olds learn now then. Its been a long time since Iv been 12 infact it has been

27-5^0 Years

[Deleted member 651465]

11-11-11 = 989

becomes

1100-110-1-1^0 = 989

 

[kPATm]

Afraid not EVF there are 4 parts to your sum and only 3 in the original

 

[Tealc]

Binary.
10000000001 - 100001 - 11 = 1111011101 (989)

Decimal
1025 - 33 - 3 = 989

The second one....

Binary.
11000 - 1010 - 110 = 1000 (8)

Decimal
24 - 10 - 6 = 8

But 12 year old? Really?

Anyway it works like this.

As soon as I saw all 1s I knew it was going to be binary. No other way it could work mathematically.
