whats the Answer
Re: whats the Answer
35
First row of cookies = 30 (10 chocolate chips x 3)
14 - 10 = 4, 4/2 = 2 (each banana = 1)
8 - 2 = 6, 6/2 = 3, alarm clock = 3
Final cookie has 7 choc chips, 3 + 1 + 1 x 7 = 35
edit- last alarm clock is 2 o clock (resolution much?)
2 + 1 + 1 x 7 = 28
edit 2 - multiplication first. ********. 2 + 1 + (1x7) = 10

Re: whats the Answer
OK. I got the multiply, but didn't notice that the 2 bananas had been replaced by single bananas - and then I didn't notice that the clock had rotated, and it now showed 2 o'clock (or, is it still just a smiley face tilted to one side)?
We all use calculators too much these days, so many would have calc'd from left to right.
And, until I tried it out just now, I'd no idea whether excel would give the correct answer without adding the (implied) brackets.

Re: whats the Answer
Please don't, or at least not if you don't want to fill their head with a shoddy understanding of algebra. 10-chip cookie, banana pair and alarm clock can all be assigned values a, b and c but the data set becomes inconsistent in the final line. You can't just tell a student to suddenly infer what a, b, or c mean. The puzzle is mathematically consistent right up until the problem. This is not how you do algebra! Please don't show them this.Holmeclaret wrote:Nice post. We'll try this with some of our Year 6 kids on Monday.
For example;
a + a + a = 30
b + b + a = 14
b + c + c = 8
all mathematically consistent, then you shout
BOOBS + PECKER + PECKER x ARSE = ?
That's a bad question.

(Lemon 3 +1 Banana)+(1 Banana x Cookie 10) = 14

Re: whats the Answer
You're right, didn't see the half bunch of bananas in the final line. But that, as of itself would make for a good mathematical discussion.Spiral wrote:Please don't, or at least not if you don't want to fill their head with a shoddy understanding of algebra. 10-chip cookie, banana pair and alarm clock can all be assigned values a, b and c but the data set becomes inconsistent in the final line.

Re: whats the Answer
Perhaps it's easier to remember that whatever the times bit in the equation is, is in imaginary brackets.
Re: whats the Answer
Agreed. You could just as easily determine that a biscuit was worth 20 but that the bits of rabbit poo on them were worth minus one each as you needed to pick them offSpiral wrote:Please don't, or at least not if you don't want to fill their head with a shoddy understanding of algebra. 10-chip cookie, banana pair and alarm clock can all be assigned values a, b and c but the data set becomes inconsistent in the final line.

Re: whats the Answer
I see 28 and I see 70 and both can be correct, but for the life of me I don’t see 10

Re: whats the Answer
Count the chocolate chips, bananas and time on the clock. It’s different each time.
