Me and Sarah think the answer is
50×10=500-75=425+4×5+4+4
=453
Looking good, but I think you need some brackets, or different number sentences… a re-think is required…
ok
((50×10)-75)+(4×5)+(4+4)
=453 🙂
Keep working on it…
There is only two 4s, not three!
I think: ((5+4)x50)+4 It is only one away soooo… I suppose it counts?
By the way, I was looking through the comments and have realised that some people have the same method as me but I SWEAR that I didn’t look at them. Please give me a raffle ticket! Please?
50+4=54×10=540-75=465-5=460-4=456-4=452
RUCSAC my friend, RUCSAC…
I love countdown QUESTIONS!!!!!!
Brilliant!
I think the answer is
[500-75=425] [425+4=429] [429+20=449] [449+4=453]
which equals 453
I think you have used some of the numbers more than once…
Remember the RUCSAC METHOD or you will get the answer wrong like me! MATHS is a great subject.
Sound advice, and I agree, maths rocks!
Count down can sometimes feel impossible however there is always a way (RUCSAC HELPS A LOT)
(50+4=54)(54×10=540)(540-75=465)(465-5=460)(460-4=456)(456-4=452)
Answer:452
Keep going…
NOoOoOoOOoOooo!!
The closest I got was 350 by doing
75 x 4 = 300
10 x 5 = 50
300 + 50 = 350
whoops I meant to post that on my account thing but forgot to change the name and email… ;-;
Whoops
Which just goes to show how careful you have to be when it comes to the internet and online safety.
Why yes it does mrs Watson
I love this countdown app in are class room
4+5=9
9×50=450
450+4=454
Marcos, we have our first raffle ticket winner – HuGe congratulations, you showed such resilience in the way you approached this problem! 😉
YESSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
She never said we had to use all the numbers
Please give me a raffle ticket
I am back! ;w;
I tried doing it in a very different way and this is what I did
10 x 50 = 500
500 / 5 = 100
75 / 4 = 18.75
100 + 18.75 = 118.75
118.75 x 4 = 475
I’m really pleased to see that you are still tackling this problem… keep going…
Hello,
I have a very good answer, though I guess I did repeat some numbers. I WANT THAT RAFFLE TICKET THOUGH!!! ;w;
This is what I did:
50 – 5 = 45
45 x 10 = 450
[5] + 4 = 9
9 + 4 = 13
13 – [10] = 3
450 + 3 =453
Alas, there is some repeated use of the numbers… you totally deserve 2 HP for your continuing perseverance…
Yayyy -w-
Well, I am not quite there YET. I have got 454. I do love a challenge
Still going!
Come on Mr. Woolton…
4+5=9×50+4=454

9×50=450
5-4=1
4-1=3
450+3=453
Well hello Yeseo, I’m loving the fact that you’re trying one of the challenges on Owls’ blog. It looks to me as if you’ve used some of the numbers more than once, but I’m going to give you 2HP for having a go anyway 😉
