Easter Saturday: Miss Marydoll's Marvellous Maths Marathon

Good morning class. I did try to find an Easter themed maths puzzle, but most were subject to copyright, so I couldn't post here.

I know the question talks circles, but they became ovals when I uploaded. That comment is to pre-empt any dispute about whether they are circles or ovals.
The important part is the calculation.

Could we please have the answers initially, then later have the process, to prove how it is done.
It means others can have a go.

Whoops. Sorry Miss, I left the page on my PC overnight and didn't refresh, so I was just seeing messages up to the last time I used it. Glad your okay.
Happy Easter to you and all GNetters

Marydoll was very quiet yesterday. I hope everything alright with her. It is not like her to not pop in a remark to her pupils. I am worried about her.

Phew!
We've got a day off from mental gymnastics!

Thank you Miss, thank you!!
Eggsactly what we need.

Have a lovely peaceful Easter Sunday.

Please miss can I go to the top of the class as I got it right? ?
I wouldn’t have suggested you copy me if I wasn’t sure it was right (DH did it for me...don’t tell Miss ?)

I think you deserve a day off Miss. Hope you have a good rest and some lovely eggs ?

EXPLANATION: The number in the middle of the first circle is determined as follows: (8-4) x (3+2) = 20. The same rule applies to the second circle: (10-7) x (3+1) = 12. Therefore, following the same rule: (9-3) x (4+4) = 48.

48

Easter eggs all round!

I'm going to take a wee break tomorrow, back on Monday if you want to. smile

Squify if Doodle is wrong, we are all wrong. I wish Miss would put us out of our misery grin

willa45 Sat 11-Apr-20 17:53:07

Sorry Doodle, I had to shut my eyes when I came in (so as not to peek) and I didn't see you. Come sit by me now....and if one or both of us is wrong, we'll commiserate and share the marshmallow peeps I brought today. smile

Squiffy Sat 11-Apr-20 17:46:27

Thank you Doodle, but are you sure you’ve got it right? It would look suspicious if we both got it wrong! ? ?

My Dh worked it out straight away. I've just got it and kicking myself . 48 .

JackyB Sat 11-Apr-20 14:59:20

I get 48, too.

Doodle Sat 11-Apr-20 14:39:40

Is the answer 48 Miss?
squiffy you can copy mine if you like. I won’t tell. ?

Squiffy Sat 11-Apr-20 14:28:58

Sorry I’m late, too! My brain hasn’t engaged itself yet, I think its cogs are in the wrong order and it can’t work out today’s puzzle ? ‘Must try harder .....’

Doodle Sat 11-Apr-20 14:24:29

MissMiss*. Sorry I’m late I was waiting for willa so she didn’t feel bad coming in late. Somehow she sneaked in without me ?
I’ll sit down now and do my sums. Not going to look at anyone’s answers till I have finished. Is it a hard one today? ?

willa45 Sat 11-Apr-20 13:44:36

Good morning Miss Marydoll and everyone! Miss, I hope you're feeling much better today. It's a gorgeous, chilly day here in Pennsylvania, USA!

To avoid the virus, I decided to start this year's garden from (mail order) seeds. A friend also grew some tomatoes in pots quite successfully last year. Two (of the many) tomato seeds I started last week (in paper cups) just sprouted, so I'm very excited about that. Flowers should be coming up in a few days too.

OK enough of that.....Finished my coffee and made it in early to class today! (Bad headache until l saw the light)......If I figured out the rule correctly, the 'mystery' number is 48!

CraftyGranny Sat 11-Apr-20 13:13:39

Why are there only three of us in class Miss

CraftyGranny Sat 11-Apr-20 13:08:58

48

Callistemon Sat 11-Apr-20 13:08:33

Oh dear, it's the heat getting to me Bathsheba
sorry

CraftyGranny Sat 11-Apr-20 13:00:05

Whoops I think that is wrong

CraftyGranny Sat 11-Apr-20 11:39:47

15

Marydoll Sat 11-Apr-20 11:24:36

HINT: The rule involves the following three math operators: addition, subtraction, and multiplication.

Bathsheba Sat 11-Apr-20 11:17:38

No, it would be 7 I think

I'm confused now, because that's what I said - 7....

Callistemon Sat 11-Apr-20 11:15:20

No, it would be 7 I think
I'm getting confused now.

Callistemon Sat 11-Apr-20 11:11:03

Yes, it would.
But the first one didn't work out so I knew something must be wrong.

Callistemon Sat 11-Apr-20 11:09:44

Only on the second one!

3 x 7 = 21
21 - 10 = 11
11 + 1 = 12

Don't try this at home.
